I don't know the complete answer here, but I can tell you about what I saw of Fran's
Seinna team of the past 2 years.
Watched them durning championship week and in the NCAA.
From what I saw, Fran had a kid named Rossiter (sp?) who played in the middle. Mid Majors don't tend to have "True Centers", so not much happening in that category.
However, I was highly impressed with the Rossiter kid. Had a nose for the ball and played hard. I saw some nice post moves and good activity for a 5 man.
If he is what Fran can bring for a 5, then Iowa will do just fine.
As far as a True 5, that definition is rare these days IMO. I would expect a 5 in Fran's system will have to be able to run a bit, so exclude big 7 foot slow footed guys. However, from the games I saw, Rossiter did have some isolation plays ran to him on the block, so expect the 5 to be able to post up on the block. I remember watching the kid play and thinking, "damn, this kid could hold his own in the Big Ten".
"True Center" to me is an Oden, Aldrich, or Shaq. A true Center is hard to come by.
Who would be a True Center in the Big Ten last year? Off the top of my head I would say Iverson maybe, uuhhhh, who else, uuhhh, Tisdale???, no not really. Maybe, uhh, not really Anyone else?
So no real "True Center".
As far as size, Iowa is lacking that to the point of being a major problem.
Iowa truly needs someone who can protect the rim at the defensive end. It would also be nice to have someone who has some go to post moves down low.
Right now, IMO, Iowa has neither. Sooooooo, does Iowa need a true center to succeed? IMO, no.
Do they need someone who can protect the rim and someone with go to moves on the post, YES.
Sorry for the long winded ramble, must be the fireworks ringing in my ears.
