As you referred to 2015, is that a bit of an outlier, too?
Here's what I mean....Zoubek and Thomas were role players. Very valuable role players. But so was Amile. So was Matt. So was Marshall last season.
Are guys like Jon, Kyle and Nolan exceptions to the rule? Kyle was a top-five kid in his class who stayed four years. IIRC, no one else in the top 10 from 2007 stayed all four years. Nolan looked at transferring after both his freshman and sophomore seasons.
Lastly, don't forget that group had their struggles in the NCAAT too. They lost in the first round to VCU, played a game eerily similar to tonight against WVU in 2008, and lost by 20+ to Nova in 2009. I feel as though if you're saying 2015 was an outlier, then it would appear 2010 might have been too.
