The reasons for him to pick UCLA, Duke, or Kansas are pretty obvious: all are traditionally powers that will likely (even though UCLA has struggled the past two seasons) be National Championship contenders. So how does UGA get on his final cut list? Well, for one, it IS his home state university. I have to admire the fact that he recognizes the value of playing in your home state; he would assuredly be a fan favorite, and his friends and family would be able to watch him in person pretty much every home game (and if he really listens during games, he can hear Van Dawgin heckling Teddy Valentine from the stands). Even though we will be breaking in a new point guard, we still have a nice outside complement (KCP) to Parker's inside game, so maybe UGA can compete as early as next season. After all, I actually like the 2012 class regardless of Parker's decision.
I would prefer to not further break down the impact of Parker's possible commitment to UGA until it actually happens. We have seen these in-state guys put UGA on their "list", only to commit elsewhere. No, he's not Shaquille O'Neal, Karl Malone, or even Jared Sullinger in terms of talent, but he is probably better than any other big man we have right now. Plus, commitments like this usually snowball, in a good way (we've seen this with football recruiting).
Hopefully, during the stagnant time after G-day and before fall camp (save for possible arrests) we will have something to cheer about this afternoon...but I'm not counting my chickens yet.
