the Bills have Marquis Goodwin a speedster with hands, Mike Williams, Robert Woods, and Sammy Watkins...talk about an embarrassment of riches at receiver and decent depth. They can throw in Chandler, Kaufman, or Hogan and go 5 wide...that's a spread lineup that should give defensive coordinators fits.
If the oline can keep EJ vertical, and open some run lanes...who knows?
