I don't disagree about the SEC, but UK has played a pretty formidable out of conference schedule, especially with UNC, Kansas, Indiana, and Louisville all locks to make the tournament. Throw in Florida and Vanderbilt twice, Mississippi State, and possibly those teams another time in the SEC tournament, and UK is plenty battle tested.
I would have agreed with this assessment two years ago as Kentucky played a pretty weak non-conference schedule (although nobody would have predicted UNC and UConn would miss the tournament), but this years team is in much better shape come NCAA tournament time.
