You never know how things can go, we just now need so many things to go right:
-Need Garcia to be a 1st/2nd Teamer All Big 10 Caliber Type Player
-Need Payne to make that big Oturu-level type jump
-Need Carrington to make a huge jump to a Big 10 caliber starting guard (Or Christie to be able to do that right away)
-Need Christie or Carrington to capably handle back up ball handling responsibilities
-Need Mitchell to be able to handle 35-40 minutes a game and play at a Big Ten caliber PG level.
-Need the bench to be capable and provide depth (Ihnen, Fox, Betts, JOJ)
-Are Fox/Ihnen going to be able to contribute at all?
-Is Betts ready to play at a Big 10 level?
-Need the coaching staff to put together successful development / game planning and squeeze the most out of this team, especially on the defensive end.
The bolded sections really just seem the most unlikely and a lot to ask.
