The way I saw it, the LB had a slow running start; Casey had the power of starting from his crouching stand.
It doesn't matter where they met (even though I expected Casey to meet the LB about at least half a yard deeper forward); what matters was that Casey got jolted backward by the collision.
That prevented Foster to cut outside early; instead, he got stucked behind the block.
It's good chatting with ya' Tailgate.
I need a break now though
