Seems like the Panthers hardly ever have a check down due to the porous line meaning the running back has to stay in to protect CAM. Just a casual observation but it seems like we have to use six to block four more than other teams. That means that CAM doesn't have a short option unless it's by design for a TE or WR. So I guess I fall into the category of 'fix the O-line' first before worrying about receivers. That said, it gets repeated often that it is easier to find quality O-line in later rounds versus receivers although I've never seen any empirical data to back that up.
As a thought experiment I would love to see a GM fork over $45 million a year to his QB on the condition that this amount will pay for the QB AND the entire offensive line (say 8 guys). The QB gets to decide how to allocate the money.
It would be interesting to see if the QB would spend lavishly on protection or keep most of it himself. Imagine some hotshot making $35 million a year protected by five UDFAs. Hilarious.
