Frankly, after hearing the description of who said this, the first person that came to mind was Ronde. He's been angry the last few weeks, so a statement like that is congruent with his current attitude.
I believe it was Barber, Blount, or McCoy.
Barber and McCoy have both had problems with the defensive side, and Blount is sitting constantly after being the #1 for awhile ..before Schiano and Co. showed up.
The other young guys wouldn't know any better, or haven't been seen in arguments with their respective staffs.
