Peyton cussing out his lineman has been on Sound FX numerous times. This is when he was with the Colts. Peyton calling out teammates (Vanderjagt, his line) is not a new thing. Cameron is not privileged like a "good old boy" Peyton to have his flaws minimized. If he calls out a teammate, specifically guys like Olsen or his linemen, they will be the victim.
Cam was trying to show leadership and instill a winning only mentallity, but I guess that was a bad thing. After the outlash he kind of fell back on that.
