That might be your problem. Personally I suck with the 4-3 but I'm 45-9 online with the 3-3-5. Like the guy above me said, USE the bear formation. Call a ton of zone if he's burning you outside. Middle plug is the best inside stuffer imo.
However, I recommend you creating 3-4 personnel out of the 335 Okie and audibling to a Bear before you get to the LOS. This theory sure works for me. I force people into the shotgun by the second quarter once they realize they won't be running on me.
