The SEC of today and of the past few seasons is vastly better than it was six-10 years ago. That makes such a direct comparison extremely flawed.
For instance, Georgia's 2013-2014 conference record of 12-6 was buoyed by a weak SEC that produced just three NCAA Tournament teams. Granted, those three teams were quite strong (Florida, Kentucky, Tennessee). The Bulldogs lost by 22, 25, 19 and 12 in their four meetings with those schools that season.
The 2014-2015 SEC was extremely weak outside of a phenomenal Kentucky and a couple other schools. Only five SEC teams made the 2015 NCAA Tournament, with Mississippi sneaking into the First Four. Only three SEC teams made the 2016 NCAA Tournament.
By 2017-2018, Mark Fox's last season, the tide was already turning. The SEC sent eight teams to the 2018 NCAA Tournament. The following season, Crean's first, the SEC sent seven to the tournament.
Is Tom Crean a significantly better in-game coach / better recruiter / better developer of talent / better person, etc. than Mark Fox? I have no idea. Can Crean recruit, develop and maintain enough talent to compete in today's much more rugged SEC? I also have no idea. The evidence is mixed.
Crean is five years removed from beating Kentucky, Kansas and North Carolina within a short span of games across two seasons at Indiana. Crean won the Big Ten conference outright twice. However, today's transfer culture and deep SEC make it difficult to know whether any of that matters.
Putting aside Crean's apparent flaws, asking someone to quickly turn a program that has made just five NCAA Tournament appearances (with one win) since 2000 into a steady force is highly challenging, if not unrealistic. Georgia has won four NCAA Tournament games since 1983. Four. Crean won six NCAA Tournament games at Indiana (two on three separate occasions), which was considered by many to be a failure.
If there's someone who can clearly provide Georgia with a better path to high level success, then Crean should go. I'm simply not convinced that there is. If people were put off by Crean's quirks and unconvinced that he could provide a vastly superior product than Mark Fox, then he never should've been hired.
