Regarding the last part, yes, of course. (Though, to me, losing Gilbert was much more devastating than losing Larrier.)
To me, it's pretty clear that Facey is the second best player on the team right now. One could argue over the last stretch of games that he's the best. He's been our best rebounder, his defense has improved a lot, and he's been scoring at an extremely efficient clip.
It gets tough between Purvis and Brimah. Both are extremely flawed players. Brimah is just as foul prone as he was coming into school, which makes him among the most unreliable players we've ever had. He's gotten better defensively, but he still makes plenty of mistakes on that end. Offensively, he is a dreadful screener, has regressed big time as a foul shooter and obviously isn't much of a low post threat. He still can't catch the ball, or even put it on the floor without turning it over. Can't pass at all. He's a disaster, in a lot of ways.
But for all of that he's still actually a player that helps us win when he's out there. Purvis does not. Purvis is shooting 33% from the field. That's unfathomably low this far into the season. He assist/turnover ratio sits at one. His PER is 9.7. His offensive rating is 89.6 and his defensive rating is 102.2. You want your offensive rating to be higher than your defensive rating. Effectively, through about 1/3 of the season, he's having the worst season - for this amount of usage - I have ever seen a UConn player have. I wish I could do more to dress that up but I can't.
It's still 11 games, though. He's a much better player than he's shown and he's still a good teammate and defender. I still believe that he's going to play well later in the year and possibly help us get into the tournament.
