Fair enough, the point I'm trying to make between the use of multiple slot, bunch and tight sets, the skill set usually needed to play slot wr i.e. quick and shifty vs 'outside' wr is utilized more often in out offense. Diggs has the skillet for both positions, but he's not the prototype 6' 4" 225lbs "outside" receiver. Davis is more prototype for outside.
But the Bills value the route running and quickness needed to play slot more than the size and strength of outside receivers, and imo you see that reflected in the styles of routes and formations.
