Don't think so. He was a different player early on. Fan expectations don't explain why his open jumpers were falling and then suddenly started missing. There have been allusions to his injuries finally getting the better of him. Can only be explained by reinjury (no evidence that's the case) or fatigue related to his long absence and injuries.
Competition was much different early on. Same with Thorne earlier last year before his injury, people thought he was a better player than he had been in his career.
Abrams played 3 years injury free, and even in those seasons, he had significant limitations, including keeping the ball too long, not pushing the ball, etc. Some of the things we are also witnessing this season.
It is not that injuries have not taken a toll on him, but fans knew about those injuries. Yet, that did not stop people from envisioning a better Tracy than even before he got injured, playing 35 mins per game, a high level B1G PG, etc. Health is not a binary thing (healthy/not healthy). You have two major critical injuries and you do not play organized ball for a full 2 years, it is hard indeed to just come back and ignore that those injuries happened. It's going to show in your conditioning and performance.
As for the game last night, TJL started and played 27 mins, in a game that was well in-hand. It is not that Tracy lost us the game. If anything, I blame Groce for not progressively giving more and more mins to TJL as Abrams has not been the answer at PG for a long time, rather than all of a sudden going cold turkey. It should have happened progressively much earlier in the season.
As for Tracy, he struggled mentally/psychological last night more than even physically. It was obvious. Groce trying to lift him up and giving him some minutes to get him mentally back, in a game that was well in hand, was no issue IMO. I actually felt good that Tracy ended the game on a positive note.
Tracy will play minutes, and we actually need him. Not only to back-up TJL but also JCL, as Nunn is not on the team and our other SG backup option (AJ) has not panned out yet.
