I can't see the team doing that much worse than they did this year. They lose the following:
Mbakwe
Rodney
Welch
Ingram
Of those, Mbakwe is the only one that will be hard to replace. And while that's a very big hole, the fact of the matter is that Mbakwe was not an offensive force this year. Probably never fully recovered from his knee injury. He also didn't box out very well on the defensive end. But he brought a lot of good things to the team that will be difficult to replace.
Rodney, Welch, and Ingram brought very little to the team this year. Ingram brought hustle, Welch brought a decent backup guard game, and Rodney's lack of a quality year probably was the ultimate key to the Gophers' relative failure this year. Defenses rarely had to concern themselves with guarding him, and he didn't really excel on the defensive end either.
Dre and Austin should carry the team, but don't count out Coleman. I like Joe's game, as long as he's being aggressive. And perhaps heading into his junior year he takes those reigns. He can get to the hoop and finish like no one else on the team, and he must do more of that. His jumper was significantly improved this year as well. EE will bring a solid rebounding, passing, and interior defensive game. If he can get more confident and figure out some consistent moves on the offensive end, he could be a game-changer.
So we have 4 pieces of a solid puzzle. Who steps up to be that main 5th player? Unknowns: Buggs, Wally, Ellis. I'd look for one of those 3 to step it up. Will Oto improve his game?
In years past, we've often looked at players going into an offseason as nobodies. Everyone was down on Al Nolen his first couple of years. Hoffarber didn't get much attention as a recruit. Damian Johnson was considered to be downright terrible by many here. Spencer was often looked down upon. And yet, just using those guys as relatively recent examples, they all surprised us as significant contributors. And then there was Dre...when that class came in everyone said that his recruiting class wasn't much. Sound familiar?
I agree that the team isn't poised to win the B1G next year or even to make a serious run at the top. However, another trip to the NCAA's is not as far away as most of this board is making it out to be. A couple players who add the most fundamental of skills: better passing, better boxing out, better court awareness - could do wonders for this team. Only need a couple of things to go our way (for once). A decent amount of success should really not be that far away.
