I'd say that DBs hate to see receivers like Irwin, but few do.  Corners will have to cheat outside to take away the out and safeties are going to have to move back over into over coverage.  All that obviously opens up the middle for everyone else, even creating more running space. 

Assuming the very realistic, we could quickly go from seeing regular Eight in the Box to Out of Necessity Nickels.  DCs--again assuming the very realistic--would have to plan for everything from Ogres and two or three tight ends to four wides with mac and Marx coming out of the backfield, and even the read-option. 

Mac, the tight ends, and Irwin could radically change our game.  The upside here is something.
