Henry is the problem. He makes Lamar and every receiver more available to a big play.
I know our CBs have been pretty good, if not great at locking them down, but we have been middle of the pack vs the run this year. With our starting LBs and NCB out still, we are asking a lot from Ingram, Williams and Spector.
This is the type of thing that Babich and McD have probably been talking about since the postgame locker room speech. McD has had Lamar contained most of the time we have played him but he's never had to deal with a RB like Henry and a QB like Lamar when it comes to the run (unless you count when he was the DC with Cam and Stewart).
