IIRC, Groce has stated in the past that he like to go up to 10 deep and play a faster pace. This probably was not possible last year, with all the injuries, but it did allow the freshmen to gain some valuable experience last year.
I could see each of the starters averaging no more than 25 minutes this year, with the exception of Hill and possibly JCL, our two biggest offensive threats.
This is how I see the minutes shaking out:
C - Thorne (25), Morgan (15)
PF - Black (20), Finke (15), Morgan (5)
SF - HIll (25), Nichols (10), DJW (5)
SG - JCL (25), Jordan (10), Nichols (5)
PG - Abrams (20), TJL (15), Tate (5)
So, basically, if Groce goes with a 10 man rotation, I could see Tate and DJW getting the short end of the minutes. However, Groce could always mix and match, based on matchups as well.
Overall, barring a rash of injuries, this is a deep team and even if there is an injury or two, they should be able to handle it.
I like this, but to start the year, I would bet Tate gets 15 and Lucas gets 5. Remember, Lucas is still dealing with an injury and being a freshman, he could struggle with the change of pace against opposing defenses.
Also, while I am still in awe of Mav's improvement, I think Thorne is the better rebounder as is Black vs Finke so I say those two guys start. As others said, there is no reason to redshirt Tate. If DJW finds himself the odd man out, then you could make the case for him.
