Just thought about this: I'd love Kelly, but unless he's a once-in-a-lifetime center prospect, shouldn't we be in position next year to also draft the best (or next best) center available? Typically centers don't go in the first round, so even if we're picking in the teens next year, we could possibly even trade back and get the best one next year. I think we need an upgrade there, but the more I think about it, the more I want to wait.
That being said, if we pick Kelly, I won't be mad at it.
