Just catching up on this thread:
This was completely expected. I've seen Beal as high as 3rd in the draft, and it would be a strange decision to come back. He'll be tough to replace, but we'll be fine. Casey Prather is extremely athletic and could get more playing time. Rosario could play more in three-guard sets. If Bennett does come to Florida, then he'll play a lot of SF.
Kentucky won't dominate the SEC next year. The #1 recruiting class is NOT enough to dominate the conference. Remember 2011, anyone? Yes, Kentucky went to the Final Four and had a great season, but they didn't dominate the SEC under any circumstance. That team had more upperclassman than this Kentucky team will have, with Miller and Harrleson.
Alabama should be good next season. They still have Trevor Releford, Levi Randolph, Trevor Lacey, Andrew Steele, and Rodney Cooper in the backcourt. In their frontcourt, they have to replace Green, but they'll be fine. Nick Jacobs showed that he could be very good on offense in the low post this season. Moussa Gueye has an enormous ceiling, but he was extremely raw, and dealing with a torn ACL didn't help. They could very well add Devonta Pollard, who seems to be down to them and Georgetown. If he goes there, they could jump into a lot of Top 25s. People having them as a probable tournament team isn't really what I would call hype, though. Lol.
