I think he's an awful human being, and in a league where scumbags like Greg Hardy finally got chased out I can't work out why a guy who beats children still has a job.
But since someone's probably going to come in with the "stick to sports" line... it's a crapshoot? He didn't do anything for the Saints because a one-dimensional old guy who can't catch didn't make any sense for the Saints in the first place (I'm still legit confused and disappointed that they signed him in the first place).
With the Cards he's on a team where they don't have any other viable running backs, at least until Johnson comes back (if he comes back this year) so maybe the workload is there. They're gonna be starting Drew Stanton for the forseeable future, so maybe they need to run it more... but on the flipside it's still gonna be a pass-first offense, AP still can't catch so Ellington will prob keep getting the passing down reps and he's still, y'know, old and injury prone.
In fantasy football I guess the question is if you drop him, who would you be replacing him with?
