It will probably be a safety who has to roll coverage to him. Also the RB's are bigger than him, when they get a shot they need to make it count. Problem is they usually overload one side where he come free. That is why Bama needs to burn them on his blitz.
Since we don't have a big JJ type receiver this year, anything to get MM or DH off the LOS free is a good thing, huh? I just asked about what a "hot read" was this summer-- but is that where that kicks in?
The hot read is where you know you need to get rid of the ball in a hurry. These days teams will send a DB and cover with a dropping DE/LB.
