Besides the fact that the "Gator Chomp" is really obnoxious and Kentucky girls are prettier.
If Wall really wants to have a chance at an Elite Eight or Final Four he needs to consider the following:
Nick Calathes is really good. He averaged a 17.2, 5.3, 6.4 last season. He also averaged almost 2 steals a game and 3.3 turnovers (good for a 1.9/1 a/t ratio). And even with a really good point guard, Florida went 9-7 in SEC play and missed out on the big dance. Is John Wall really that much better than Nick Calathes? Can he be the difference maker on a team where point guard was a strength (maybe THE strength) last year?
While the only playmaker (outside of possibly Calathes, who Wall would be replacing) that Florida is losing next year is Walter Hodge, they aren't gaining that much. Newcomers expected to contribute next year are stud SG Kenny Boynton, and Vernon Macklin who transferred from Georgetown. Boynton could be a big contributor, but as with all freshmen, who really knows until the season starts? And while Donovan has talked highly of Macklin, it would be a push to expect him to average double digit points (he averaged just over 3 @ Georgetown his freshman year). They are not a very deep team and Wall would be more of a measure to hold the team together rather than the final piece of the puzzle.
If Gerald Henderson comes back to Duke, Wall could make them a Title contender immediately. They won 28 games, have a great nucleus returning and could make a serious run. It's also close to home (and his mother). Without Henderson, Wall makes them a very good team, but I don't think they have the players to do serious damage in March.
Kentucky needs a point guard. In fact, if Jodie and Pat come back, that's pretty much ALL that Kentucky needs (besides maybe a bit more time getting used to the DDMO). Enough said.
I think that if playing in March is a consideration for Wall he should pick either UK or Duke. Florida is not very deep and didn't do that well last year with a great point guard.
Feel free to disagree and point out any mistakes I may have made.
