This is so logically strained.
On the one hand, you are criticizing our lack of depth. On the other hand, you are discounting Thorne because in a different universe he might not have come here.
But Thorne did come here, and he played great until he did get injured. If he didn't come here, someone else would, and if that player was injured, it would also affect our depth.
There's no evidence to support the bolded, that's purely speculation that Groce had another transfer in the pipeline to fill in at the 5. And in looking at the stats, Thorne played well with 13.4 / 8.4. You and I may define "great" differently.
Each team can have up to 13 scholarships per year, and having five bigs is pretty good depth in the frontcourt. If you have more than that, the other positions become thin. When three bigs are injured, even the deepest teams have depth issues.
Bodies in uniform <> depth, and I'm not sure where you get 5 from. Mav, Black, Finke, and Thorne are the bigs we started the year with.
You discount Darius just because we don't know what his contribution would have been. Well, that is true for every player, and it varies from game to game. Some players exceed expectations, others don't.
I think you're missing the point. A number of posters lament the loss of DP, but we don't even know what we lost. He played zero minutes for the University of Illinois, so there is no baseline on what his loss means to the team. It's also on Groce for taking a flyer on a guy who had a history of behavior issues. Hindsight's 20/20, but there were warning signs and DP even got a second chance which blew up in his face.
That's why they play the games on a court and not on paper. At the beginning of the year you didn't know what to expect from Finke, either, or you had already made up your mind before giving him a chance. Just because you don't know ahead of time what to expect from a player does not make that player expendable.
For the record, I had very high hopes for Finke and he has exceeded them. A RS frosh with his offensive abilities should be formidable, and so far he is. Your mention of him is fairly irrelevant however, and FWIW, Finke's defense is...not good, to put it mildly.
My post was essentially in response to your earlier statement "His first three defensive teams were good or above average at least I believe."
But those first three teams weren't good defensively, and barely approached average. The reason they weren't is either
a) he isn't bringing in guys who can play defense at a B1G level
b) he isn't coaching up the guys who can play at that level
c) both of the above
You absolutely cannot lay all of our defensive woes on the injuries. If the next man up cannot play defense, cannot hustle, cannot work for a rebound, they aren't the right guys to have on the floor (or the bench), and that is on the coach, period. No one expects they 4th and 5th guys off the bench to perform at the same caliber as the guys that should be starting, but I don't think it is unreasonable to expect them to perform at a higher level than what we're seeing.
I like Groce, I want him to be the answer, but our defense is terrible. You cannot win in the B1G with terrible defense, and that's on him and his staff, one way or another.
