I think Albert Wilson, Jakeem Grant, and Mike Gesicki would complement each other well in 12-personnel.
Jakeem forces a defense to think and hesitate when he is on a jet sweep action. Kansas City took advantage of that with Tyreek Hill and Albert Wilson by putting the latter in position to lag behind Hill’s sweep action and then take the shovel pass cutting to the inside of the edge-setting defender (who sets the edge really widely because of Tyreek’s speed).
Kansas City also took advantage of Tyreek’s pure speed on go routes to push shell coverage really deep, and then work Albert Wilson underneath it as he had the ability to be really dangerous after the catch. They would also work Tyreek and Albert on opposite sides, forcing the defense to spread out because of their speed, and that gave them room to work Travis Kelce underneath against man or zone coverage.
One thing about Gesicki is when you look at his Penn State tape, for example there were plays against Michigan State that come to mind, they split him out wide and ran him on routes that you'd otherwise see DeVante Parker running in Miami. That's another thing that makes me believe that you could work in a 12-personnel package with Jakeem Grant and Albert Wilson at WR, along with Mike Gesicki and Durham Smythe. You could definitely split Gesicki out wide and turn that into formations you'd otherwise associate with 11-personnel.
That package would give you big pluses in screen blocking. Whatever you think of Mike Gesicki as a blocking tight end, if you were to put him on the perimeter on a Bubble or Tunnel Screen, I'm sure he could be at least as good at blocking as DeVante Parker. We know that both Jakeem Grant and Albert Wilson will block their asses off, although you do have to pay some mind to the matchup. As things stand both Laremy Tunsil and Ja'Wuan James are so mobile that they get out to the perimeter well on those screens, so there's a good inherent team advantage regardless of personnel package. Of course Durham Smythe was a very accomplished blocker himself at Notre Dame.
They key is you're not trapped into screens with that 12-personnel package because they can run other things. With Albert Wilson and Jakeem Grant on opposite sides, you can stretch the field horizontally and vertically, providing space for Gesicki to get open. Depending on the amount of cushion you see, you could take the underneath routes all day. If they're aggressive, you could blow them out with a deep ball easily. You could work the aforementioned jet sweep/shovel pass combo (and I'll remind you that Mike Gesicki has experience with shovel passes at Penn State).
So many things you could do out of this, that you could throw it onto the field for a No Huddle series and have a nice number of options to get out there.
