I don't have a big problem with his use of Jones. There are only a couple kicks each game that are returnable so the sample size is small. It looks like he's only actually returned 17 kicks this year. He had bad mental errors early on which could have been partially others' fault, and some fumbles which are maybe fixable. It's kind of like fumbles for running backs -- we hated how BB would immediately bench Ridley based on a small sample.
BB did bench him for I think three games earlier in the year and I'd imagine he's not dropping every kick in practice. The team has a huge lead on the division and should win most games comfortably. The upside here is finding a good reliable kick returner with breakaway upside who isn't Edelman. I think that's probably worth a fumble against the Rams when you have a decent chance of recovering it (which they did) and they literally can't move the ball against you anyway.
It would really suck to lose Edelman on a punt return because you had no one else. Maybe that's where we end up anyway but I'd like to give a guy who returned 4 punts for TDs in his senior year a fair shot at being a threat for the Pats.
