There's a reason they are ranked #1 and that's part of that reasonāyes, Elite 8 three times in a row. Hell, they've made it to quarterfinals five of the last eight years.
When I started pointing to the amount of talent coming out of SEC states a month and a half ago one of the teams I looked at was the 2007 Gator team. That was a damn good ball team. One thing that struck me about that team is even though Florida produces the third most D1 talent of any of the states within the SEC footprint (#1 TX, #2, GA) their starting five had two from TN, one from FL, one from NY, and the other from PR.
Donovan has all the talent in the world around him and still is reached out to other states to build what he has now.
