He is shooting more this year than he did last year, but part of that is that he is playing more minutes (all of the minutes in recent games). His per-40 shooting numbers are not as greatly improved, however:
2015-16 2016-17
Field Goal Attempts: 9.4 10.7
3 Point Attempts: 4.3 4.2
Free Throw Attempts: 3.3 3.6
Additionally, if you look at advanced stats, there isn't much improvement year over year there, either:
2015-16 2016-17
Player Efficiency Rating: 20.2 20.9
True Shooting Percentage: .606 .611
Effective FG Percentage: .572 .571

Now I'm not really trying to pile on to Tyler here, and I don't think that he's the biggest reason the team has struggled this year. I do, however, think that it was reasonable to think that he would make a bigger jump from freshman to sophomore year than he has. In order for this team to have any sort of success, it needs Tyler to do more than he is currently doing. Maybe that's asking too much though; I don't know.
