Just the latest unjustified assertion of authority by Goodell, who in this case is carrying water for the NFL's minor league system (aka the NCAA))
It's dangerous ground in that Goodell has now set a precedent with the Pryor ruling, and his judgment and decisions on punishment had best be in line with that standard going forward. Will he hand out discipline to every college player -- or head coach (hello, Pete Carroll?) -- who attempt to enter the league even while the cloud of alleged NCAA violations or illegalities still hang over their head? If not, it's only going to add to the charges that Goodell has wielded his considerable power too arbitrarily and inconsistently in some high-profile cases.
Absolute power corrupts absolutely
