Start with the o-line. You want to find an Otah type RT, a monster who makes it difficult to see around him. When Otah mauled someone, they had no choice but to give in to his will. Williams would hide behind that massive monster, and then race out from behind him depending how the rape was going, and LBs had trouble seeing Williams. Put Cam and Stewart in the read option behind an Otah, and you have a run play that will take 9 in the box to slow down. No team, I don't care who they have on defense, could stop that run play. Period. The problem is that Otah was a HOF level OT who doesn't come around that often. But we can get as close as possible early in the draft if there is one.
With LT the standard is Jordan Gross. Solid, dependable, intelligent, friendly, and on point with his pass protection 95% of the time. He had a few terrible games, the Redskins game comes to mind, but the LT needs to put the QB at ease by protecting his blind side with consistency. Find a vet in FA, or via the draft.
The OG situation is a problem. Amini can't block stunts and blitzes well. That puts Cam in serious danger, and brings a halt to our offense far too often for it to be effective against certain teams. We need an OG who has decent power, and can block stunts and blitzes much better than Amini. The only sure fire way to get a guy like this is in FA. The draft is risky and OGs shouldn't be that expensive in FA.
The o-line would then be good enough to allow for the Panthers to become a great team.
Add a deep threat WR and you've really got something.
