I think a healthy and in sync Jones/Reeder is a better 1st down or run likely defense. For as much as we all hate on Reeder, he does some things well, those things just do not involve covering good tight ends or backs.
I feel like with him in there, we have more size to take on the run game.
I do not think Reeder will be a big part of next year's team. Linebacker has had its share of injuries this year.
