I'd be much more comfortable with Fournette irt trying to keep Cam alive than McAffery. Or OJ Howard for that matter.
Fournette could be a workhorse. McAffery is basically a guarantee they're going to keep running gimmick crap that gets Cam killed
I don't see that happening. Ingram should remain the starter and be the primary pass catching RB (not AD's thing). At his age, AD will most likely compliment him as Hightower did and get his 12 or so touches a game.
Regardless, good move by the Saints at that price and a nice 1-2 combination to have.
