2020 Fantasy Outlook
During the 2019-20 season, Theis transitioned from helpful reserve to reliable starter. In Theis' first two seasons in Boston, he started five of 129 games. But last year, Theis started 64 of 72 regular season games and all 17 playoff games for Boston. His playing time expanded to 24.1 minutes per contest, which led to career highs in points (9.2), rebounds (6.6), blocks (1.3) and three-pointers (0.5) per game. That said, Theis was the fifth option on offense for a Boston squad usually sporting Jayson Tatum, Jaylen Brown, Marcus Smart and Kemba Walker as his fellow starters. And now that Boston has added Tristan Thompson, a slight improvement over departed Enes Kanter, Theis could see a slight dip in playing time. Expect Theis to have the upper hand over Thompson as the starter to begin the season, especially with the shortened off-season. Also, hopefully, Theis can continue to avoid the injury issues that plagued the German center during his first two seasons with the Celtics. Read Past Outlooks

Personal Bio

Daniel Theis was born in Salzgitter, Germany, in 1992. As a youth, Theis was more interested in soccer than basketball. His father and older brother Frank convinced Daniel to focus on basketball. Frank and Daniel would eventually play hoops professionally together. As an 18-year-old, Daniel played his first of two seasons with Braunschweig's youth development squad, where he played side-by-side with Frank. A knee injury forced Frank to quit basketball (he is now a middle school teacher). Daniel is a three-time German National Champion, with all three titles coming while he played for Brose Bamberg. Theis and his family supports the charity Room To Grow, which helps underserved parents by offering them essential resources needed to raise children.

College/International Summary

Before joining the Celtics, Daniel Theis played professionally in his home country of Germany for Basketball Bundesliga. As an 18-year-old, he played his first of two seasons with Braunschweig's youth development squad, where he played alongside his older brother Frank Theis. During his second season, he was named All-2 Pro B Most Improved Player by Eurobasketball.com. That led to two seasons with Ratiopharm Ulm, where he earned the BBL's Best Young Player award during his second season. The big man then signed a three-year deal with with another German Bundesliga club, Brose Bamberg. With Brose, Theis would win three straight German championships. During his last season in Germany (2016-17), Theis would average 9.5 points, 5.2 rebounds and 1.1 blocks over 71 BBL and EuroLeague games.

ANALYSIS
It seems likely Theis suffered the injury at some point during seeding games or the playoffs, though he didn't seem especially hampered by the issue. He put up numbers as expected in the postseason, averaging 8.9 points, 7.1 rebounds, 1.5 assists and 1.2 blocks in 28.2 minutes. According to the team, Theis is expected to be a full participant in next season's training camp.

Past Season Summaries
2019

After spending his first two NBA seasons in a bench role for the Celtics, Theis stepped up into far more responsibility in 2019-20, starting 64 of his 65 games in the pandemic-shortened campaign. The returns were all positive, as Theis set career highs in practically every category. His counting stats jumped up to 9.2 points, 6.6 rebounds, 0.6 steals and 1.3 blocks per game. And his efficiency improved too, as Theis set career highs in both field-goal percentage (56.6) and free-throw percentage (76.3). The 6-foot-8 center opened the season on a shot-blocking spree, piling up 17 swats in his first eight games, including a career-high five on Nov. 5 against Cleveland. Theis went on to contribute double-digit points on 31 occasions and record seven double-doubles. Twice Theis dished a career-high six assists, which included an eight-point, 14-rebound, six-assist effort on Nov. 20 during a road loss to the Clippers. In his biggest game of the year, Feb. 21 against Minnesota, Theis exploded for 25 points and 16 rebounds -- both career highs. Once playoff time rolled around, Theis remained in the starting lineup for all 17 games of Boston's run to the Eastern Conference finals. He double-doubled with 13 points, 15 rebounds and a pair of blocks in a Game 1 win in the second round against Toronto, later adding a 15-point, 13-rebound double-double with three blocks in Game 5 of the conference finals against Miami.

2018

For the second consecutive season, Theis provided impressive scoring, rebounding and defensive ability in a very limited role for the Celtics in 2018-19. He posted 5.7 points, 3.4 rebounds, and 0.9 combined steals and blocks per game despite actually seeing his minutes reduced from the prior season (from 14.9 to 13.8). His per-36-minute averages of 14.8 points, 8.9 rebounds and 1.7 blocks again suggested that he was deserving of additional playing time. As he had in his rookie season, Theis shot very efficiently, delivering a 54.9 field-goal percentage, and he became far more accurate from long range (38.8 percent). The 6-foot-9 German missed eight of Boston's first 15 games due to foot injuries, but he returned to serve as a reliable backup at center and power forward. In a Dec. 8 blowout win at Chicago, Theis scored a career-high 22 points to go with 10 rebounds, five assists and four blocks. That was also his only double-double of the year. Theis went on to appear in seven of the Celtics' nine playoff games, averaging 1.7 points and 1.4 rebounds over just 6.0 minutes per game.

2017

After seven seasons of Bundesliga and EuroLeague basketball, Theis signed a two-year agreement with the Celtics ahead of the 2017-18 season. The 25-year-old NBA rookie appeared in 63 contests for Boston, starting in two of them while providing defensive grit and energy off the bench. Despite averaging just 14.9 minutes per game, Theis put up averages of 5.3 points, 4.3 rebounds, 0.8 blocks and 0.5 steals -- good for per-36 averages of 12.7 points, 10.5 boards,1.8 blocks and 1.2 swipes. He was efficient both from the field (54.1 percent) and from the line (75.3 percent), and Theis even showed some long-range shooting ability, sinking 0.3 threes per game at a 31.0 percent clip. He picked up his first NBA double-double Nov. 1 against Sacramento, collecting 10 points and 10 boards in just 18:18 on the court. On Dec. 23, Theis set his season high in rebounds with 15, adding 10 points for another double-double. On Feb. 23, Theis scored 19 points with seven boards, two steals and two blocks in just 20:55 on the court. On Mar. 12, Theis underwent season-ending surgery to repair a torn meniscus in his left knee, which caused him to miss the Celtics' deep postseason run to the Eastern Conference Finals.

Past Fantasy Outlooks

2017
The 27-year-old Theis has proved two things over his first two years in the Association. First, he's an effective big man off the bench, contributing with solid defense, strong rebounding and even decent three-point shooting. Second, he's brittle, having missed 35 games in two seasons due to knee issues and other ailments. With his injury history in mind, don't expect Theis' roughly 14 minutes per game to change much this season, despite the departure of Al Horford and Aron Baynes. Coach Brad Stevens will value Theis' presence, but expect sophomore Robert Williams and French import Vincent Poirier to also plenty of floor time backing up assumed starter Enes Kanter. Plus there is always the outside chance Boston decides to experiment with rookie Tacko Fall at the big league level. For Theis, expect another season of brief spurts of productivity in between absences due to nagging injuries.
Theis emerged as a meaningful bench contributor in his first NBA season, appearing 63 games and making three starts before a knee injury cut his season short. While Theis wasn't Fantasy-relevant in most formats, he averaged a double-double per 36 minutes and flashed a better-than-expected stroke from beyond the arc. Theis is expected to be fully recovered by the time the regular season rolls around, but with Al Horford and Aron Baynes both back, he'll have a difficult time seeing more than the 14.9 minutes per game he averaged as a rookie. Barring an injury to one of the aforementioned bigs, Theis can be ignored in most Fantasy formats.
German power forward Theis is expected to earn a reserve roster spot with the Celtics following the three-for-one deal that brought Kyrie Irving to Boston. The 6’9” star from Brose Bramberg of the Euroleague has the potential to provide some much-needed rebounding and rim-protection for the Celtics. Theis was an important contributor on a team that won three consecutive national titles in Germany in addition to the 2017 German National Cup. In 2015-2016 and 2016-2017 he was a German BBL All-Star Starter and named the Defensive Player of the Year in 2016-17. He was also named the Best National Player in the BBL in 2015-2016. Theis will battle fellow international players Aron Baynes and Guerschon Yabusele for backup power forward minutes. The Irving trade does free up potential minutes for Theis. Expect Coach Brad Stevens to experiment with lineups throughout the season, which might results in both 15-minute games and DNPs for Theis.
