I think the correct question is what is the role of a Slot Receiver in Dorsey's Offense. I'm not sure it has much to do with McKenzie. Daboll used Beasley as a guy who would go out five yards right off the snap and turn around. I think McKenzie can at least do that! So can Shakir. In Dorsey's Offense, that role has been replaced by a late leaking Singletary who presents himself to the QB as a check down five yards deep over the middle.
