Let's start there. Jeff Teague is a career 35% three point shooter although he had an amazing 40% season in 2015-16. He also does not seem to mind taking a backseat on the team as evidenced by his success with those great Hawks teams and also last season with Paul George. He is a solid point guard that can do lots of good things for your team. He was great offensively with Indiana last season averaging career highs in assists and free throw attempts while averaging 15 points a game on 11 shots per game. He seems to be a good fit for the Wolves in that he does not need the ball a great deal to be successful. He plays hard defensively, but as seen in the Cavaliers series he can hurt you defensively in the wrong matchup. The Cavaliers kept going to those Kyrie and Lebron pick and rolls, which left poor Teague matched up with Lebron and he had no chance.
When you dig deeper you can get a better picture of what Teague can do for your team. 28 players averaged over six pick and roll possessions per game and of those 28, Jeff Teague rates very well. His pick and rolls led to points more frequently than all of the players except for four and he scored 0.98 points per possession out of the pick and roll. As a pick and roll partner for Karl-Anthony Towns, Teague may not be the passer that Ricky Rubio was, but he is a much better shooter and more of a scorer. He is a great pick and roll player that can keep defenses honest on the pick and roll and not allow defenders to leave him open or he will make them pay. As an isolation player, Teague rated out quite well scoring 1.02 points per possession and rating out in the 84th percentile among all players. Teague uses his quickness well and although he is a smaller guard, he finishes well when he gets there. He also has a nice mid range jumper.
It is hard what to make of Teague's fit with Jimmy Butler. Paul George did not run the pick and roll often preferring to play more of a spot up role, but Butler runs a lot of pick and rolls. As a matter of fact, he ran more last season than Teague. It will be interesting to see how he plays next to a player like Butler and if he becomes more of an off-ball player for the Wolves. Teague will help the team and I see him as someone that can improve the play of Andrew Wiggins and Towns through his pick and roll skill set and his underrated ability to pass the ball.
