What is the proper way to defend the infamous Bama "dump pass" to Richardson?

I've watched a significant amount of Alabama football this year, as I'm sure many of our fans have. The "dump pass/check down" (perhaps there is a more appropriate technical term) to Richardson appears to be a staple of their offense.

It typically occurs as follows: Richardson lines up in the backfield as an extra blocker, either to pick up blitzers or chip defensive linemen; the ball is snapped and the Bama WR's run their routes, clearing space and creating a natural void between the LOS and the now retreating defenders (linebackers and DB's) who are reacting to the routes; the Bama oline holds off the oncoming rushers; Richardson leaks out just beyond the oline; McCarron looks downfield briefly and then (either because the play is designed this way or the downfield routes are covered, I don't know which) flips the ball over the line to Richardson, who is uncovered; Richardson turns and finds himself with five or six yards of space; Richardson runs and by the time the DB's and LB's have closed, he has recorded a significant gain.

Every time I see Bama churn yards on this play, I have the eerie feeling that I am playing EA NCAA 12 online against the world's biggest cheeser. But it's effective, and you can't fault a team for being effective.

What is the right way to defend the dump pass/check down? Do you send an extra rusher every time Richardson is in the backfield, either to occupy him as a blocker or to sack the QB before he can dump it off? Do you spy Richardson? Play zone so that the LB's are always near the LOS?

Seriously, how do you stop it? Is there an orthodox, effective way to defend it?
