I saw the Carson interview and he really sounded... kind of scared! I actually couldn't believe what he was saying primarily because you don't normally hear those words come from an athlete. I really believe 83-Steelers-43
said it best when comparing Ben and Carson though.
Marvin could really be losing some faith in his QB and getting irritated, especially when he sees what happened to Ben and Ben is already on the field again. I really feel his comments were to get Carson thinking and get him on the field again, however, a lot of it has to do with what you said about the coaches trusting their players and knowing how to handle certain situations. Marvin has no control right now and his trust in Palmer is definitely on the decline.
