If this looks like a defensive nightmare what was last year. Interior D will be significantly better regardless of the rotation. This will help our perimeter defenders a lot. Also it is not like we lost any real defensive stoppers from last year. More athleticism means better defensive potential.
As for rebounding Franks is no Hawkinson, but he is better than many people think. Despite Hawks double doubles our team rebounding was not good last year. We could be better this year with even a couple of guys averaging 7 per game.
I would be surprised if Ergas is ahead of Acquaah in the rotation. Also, I know nothing about Hinson other than reportedly being a good shooter and leading scorer on a good JC team. I would expect him to be a starter or early off the bench for some instant offense.
A lot depends on how quickly new guys figure things out
