Kentucky has so much talent coming back on top of that class it's crazy. The only thing, if there is anything, that would hold them back a bit is how the other players mesh with the Harrisons. Other than that UK is a monster. UF though is loaded as well and will challenge them in the SEC
Kansas picked a good year to be young I suppose as the conference as a whole is not that great. Not to say KU doesn't have a ton of talent though, just that if this was a year where there were 3-4 veteran top 25 teams in the conference KU might struggle more than usual.
