Im not on board with the disguise the rusher concept--when that player is your best outside pass rusher. Look at the Chiefs--Sutton continually will put Houston in one on one man versus rushing him. This is a disaster imo--your best outside pass rusher needs to be rushing the passer. Quinn occassionally covered--I remember a couple plays from the second Seattle game. But pressure wasnt an issue at all in that game.
Basically, I think disguise is good but you should not put one of your best players on a assignment that does not maximize their skillset frequently.
