I don’t think the key is the running game. The Patriots have to figure out a way to be more explosive in the pass game to setup the run. Healthy Gronk and Hernandez certainly help – if they ever stay healthy. But I think the Patriots have to look hard at Welker and their offense. What you saw before Hernandez got hurt against the Cardinals – Lloyd, Hernandez, Gronkowski and Edelman – makes them much more explosive all over the field. They need upgrades to Lloyd, and if Edelman can’t stay healthy, someone quick and athletic after the catch in that spot. Do you give up the safety of having Welker to go for broke – not in the regular season, but in the post season – by changing the offense and personnel? I think those are the big decisions looming over this team and Belichick.
