LG,
Avoid basketball debates at all costs. College basketball is now a guard dominated game because the big men that could dominate and overshadow the guards all reside in the NBA. Dominant big men, to your point, are worth their weight in gold, but there just aren't any, so they with the best guards win.
I know, you can't wait to shove UF in my face, but they win, IMO, because they can play great D when they need and they have a very balanced attack, so defending them is extremely tough on a given night. Their inside play is not the reason they're great.
