Think it's more like sark is an incredible play designer and having guys all over the field with specific traits helps him create cheat codes in the offense...
Also, like @Gerry Hamiltonsaid, in this new era of the portal you gotta pivot QUICKLY. Once we couldn't get Baugh and the michigan OLs I think Sark just said screw it, we're gonna put so much speed on the field and so many mismatches that you're not gonna able to just load the box and stop the run/pressure Arch cause if you do you're gonna get burned.
Remember that all offensive guys do is try and create explosive plays, while all that defensive guys do is try and limit explosive plays... good luck blitizing Arch or loading the box when you have horizontal threats at all levels... from the RBs to the WRs now that Wingo has a Coleman... defenses are gonna have to choose on who to focus on... is it gonna be the vertical threat of Coleman or the horizontal threat of Wingo? Good luck to them.
