You missed the part where I said "The RB usage will go up with McCaffrey coming to town." Yes, CAR will put up better numbers by trying to address a problem area. However, IMO, it would have been better for McCaffery to be in a spot where he slotted in and could capture or replace existing production instead of going somewhere where they will have to create production where it didn't exist.
Put a different way, Zeke Elliott going to DAL and taking the numbers Murray had was a fantasy dream straight from a feel good Disney movie. We haven't seen that type of RB productivity in CAR in recent seasons.
Maybe the Panthers do reshape their entire offense to run through McCaffery. I don't expect that to happen, but he should do all right in CAR. I happen to think there were better landing spots for him than the Panthers. And just because he was the 8th pick in the draft does not mean he will be anointed as a superstar.
Todd Gurley, CJ Spiller, Trent Richardson, Darren McFadden, Ronnie Brown, Cedric Benson, and Cadillac Williams were all Top 10 picks. In fact, they were 7 of the 10 backs that were Top 10 picks since 2005. None of those guys really panned out or turned into home runs (although the jury is still out on Gurley). The other 3 were Elliott, ADP, and Reggie Bush.
I really don't have much of an informed opinion based on what I have seen, as I have only seen highlights of McCaffery and I don't often get to watch the Panthers. My comments were based mostly on looking solely on the numbers.
