Worst thing that ever happned to Martin was the competitive showing in Maui. Gave Tennessee fans false hope and now reality makes it look like the team has regressed. Truth: They weren't any good to begin with.
Maui vibe is different. Small gym, teams usually shoot well, early season refs - the first Memphis game, for instance, was dictated by the fact refs called 10 million fouls. Now we have bigger sample size and Tennessee has only beaten really, really bad teams. Has lost to good teams, mediocre teams and even one bad team. That means the players aren't good enough.
I don't know if Martin can get it done or not. Never made an NCAA Tournament at Mizzou St, so time will tell. But coaching or not, Memphis is a much better team than Tennessee with way more talent this year. Will take a few years of recruiting to fix that.
