So, you disagree that a backcourt with five--and possibly six--returning guards lacks depth? ; )
Ultimately, it doesn't matter what you or I think -- it only depends what Green thinks. And not just Green, that's how it works with every recruit. Every year I see fans pine for recruits to come here to fill some perceived hole in our roster, ignoring that it is up to the kid, who often doesn't view things in the same subjectively black-and-white terms that fans do. We aren't a selector school that can stack multiple highly rated players at the same position, despite being in the top 5 for all time wins. Never have been, probably never will be.
I'd like to see Green elect to come to SU. There'd be some nice "closure" to this story if he did. I actually heard that he may have put some feelers out to the SU coaching staff this past summer, before opting to return to Kentucky for his now abbreviated sophomore season. But if the coaches aren't receptive now [which is understandable, given that they were snubbed twice], then it won't happen.
Or if Green opts for what he perceives to be greener [pun intended] pastures somewhere else, then the readiness of Carey, Goodine, Girard, Boeheim, etc. doesn't matter a whit. People can rationalize the decision however they choose -- but it will ultimately be up to Green, as we agree.
