IMHO, there may be a little more talent on the roster than what it might seem on the surface. The biggest thing - pun intended - is no big, other than Roby. (I expect him to return, but he will be more impactful if he does not have to play the 5 position). Roby and Allen are known commodities, and with a different coach and scheme they have the ability to take a step up in production. The transfer, Burke, can be the 3rd scorer. Since he is sitting out this year, that is conjecture. If Jervay Green stays committed, that is the 4th scorer. So, theoretically, there is a possibility of doing OK in regard to the top 3-4 in point production.
Harris, Thorir, and Akenton are decent role players - in the right situation. Harris and Thor showed what they could do when forced into action. Personally, I thought they should have been given more minutes all year long. Heiman has potential. Gotta gain some bulk. He was one player I thought could have provided more help, but for some reason he got lost once B1G play started. When we hit our early season losing streak I don't think Miles had the ability to take a chance on him. Karrington was out all year with an injury. Not sure what he can provide. Supposed to have offensive skills.
We have the potential to be a decent offensive team, which will keep us competitive. Hard to see where we can get rebounds and play half-court defense. Without a big coming in, it wouldn't surprise me to see a very aggressive defensive scheme and full-court pressure most of the game.
