I said it a few weeks ago. There's a well defined line between the Top 6 teams in the country and a handful of teams after.
Auburn, Florida, Tennessee, Alabama, Duke, and Houston are separated. Michigan State was one of those teams on the fringe with St. John's.
Its pretty wild that this year there were no hiccups with that top tier of teams. St. John's was the only one that hit a speed bump, but there was a reason they weren't ranked highly most of the season. They benefitted from a light Big East.
