Very good point. Maybe RIvera was not intending to slight his OC, he was simply stating that his OC would be a better listener. HOWEVER, then your second point becomes more obvious. Was he blaming Chud for last year's frustrations on offense--that he was not listening to others? If that is the case, then he basically told the press that he was not regulating the offense--He trusted Chud and was stooooopid to do so.
Coming off 2011, the offense was sizzling and Cam was ROY. The league adjusted to Cam and the offense, but Chud did not adjust to the league. Rivera did not have veteran assistant coaches and did not have the knowledge about the offense to regulate adjustments.
Believe it or not, it was the opposite.
CHUD, actually adjusted to the league first, before anyone did anything else. That's what makes this (Chud, Rivera, and the offense in 2012), so crazy and perplexing.
Rivera, admitted in a NFL.com article to Albert Breer (earlier this year), that Chud--in anticipation of NFL defenses in 2012, decided to make the Read Option the Preferred/Go to offense, despite the fact that Cam and the offense were so successful in more conventional (including under center), two tight end sets his rookie year. Can you believe that?
It was Cam's Rookie type offense, that the team actually fell back on (with the spineless/clueless Rivera in fear of losing his job, finally making a move), that the team utilized during the second half of the season. Remember that!
The 'Cam Adjustment' by NFL defenses is really a fallacy. Maybe that would have been true, if Chud didn't attempt to rely on the Read Option, and changing up the formations as he did? However, it was the older, more conventional sets--Cam had in his rookie year, where he's seen most of his NFL success so far. That's what drives knowledgeable Panther fans and observers so crazy (especially with outside, wayward critics attacking Cam, having no idea Chud's, Rivera's input and complicity the first half of the season).
