Wannatache is having success at Pitt this season.
Little Nicky has his (ahem still at least half Mike Shulas) team undefated.
Cam has a good offense in Baltimore
And Rick Spielman has assembled a good team in Minnesota.
I guess in Daves case you could say he's better at relating to college players.
In Rick's case you could say his authority was limited in miami (he wanted Anquan Boldin instead of Eddie Moore).
Cam is undoubtedly a better oc than head coach.
And as for the waNICKer you could say his method has limited success in the short term at the college level.
