It's been discussed on here whether Morgan or McGary should start (when both were healthy). In Morgan's absence, I think we can all agree Morgan is the starter and was extremely undervalued for his defensive prowess.
Now, Caris is stealing away Stauskas's minutes and stepped up big time after the injury that Nik had early in the game. There's no doubt that Stauskas has been a liability on defense and offensively seems to be in a bit of a slump as well.
So, If you're Beilein, who do you start against Purdue (assuming Stauskas is healthy)? I love Caris coming in off the bench, but it seems to me he has really stepped it up on defense. Stauskas played horrible helpside defense against MSU and was responsible for 2 easy baskets they had early in the game. So if I'm Beilein, I start LeVert over Stauskas.
