I posted a question in the general section concerning the rules regarding attacking the pitchman. The general consensus is that it is legal to knock him down, but not to tackle him before he has the ball.
My next question, for the DC 4-3 crowd, is how would you assign this. Spread team, in 2x2 or 3x1, with the slot man backing up in a cowboy motion to pitch depth. We have CB in bump on the #1, SS/WS spliting the #2, OLB generally assigned to the pithman. Would you send the OLB hard to knock the pitchman down once we see that motion, or leave him off the line?
