RB Jahmyr Gibbs, Alabama
There is an alternate universe where RB Clyde Edwards-Helaire became the back for us that he was for LSU. He offers some fundamentally sound running between the tackles, but is the third down back for eternity, whipping wheel routes and juking angle routes, creating separation in short yardage and chunking off 8 yard gains in near-unstoppable chemistry with Mahomes. Naturally, that never came to fruition, as (I'm guessing) his pass protection was so poor they never put him in obvious pass situations, and his between the tackles running, while initially exceptional, collapsed almost entirely after his injury his rookie year.
But we can rebuild him. We have the technology. And his reborn form would be Jahmyr Gibbs. A fundamentally sound running of a somewhat slight frame to allow him to get in and out of jukes in a hurry, Gibbs' primary talent comes from being effective in the passing game. He seems to have the route-running ability of a slot receiver sometimes, with far more speed upside than Edwards-Helaire had. He has great hands, good feel for zones, and far too much quickness for even the average NFL linebacker. He may be a more slight, but faster version of RB Joseph Addai.
I'm warning you: don't underestimate this as a future Chiefs pick. The Chiefs clearly value this type of running back (some might argue over-value). The Chiefs clearly believe they need this player. McKinnon is the closest we have, and he's entering the offseason as an oft-injured, 30 year old free agent. Edwards-Helaire is literally on the roster now but he's likely to be traded. And the Chiefs clearly value the position so much they were willing to spend a 1st round pick on it in 2020. Now, I don't value this type of RB as much as the Chiefs do, but I'm just a guy in a chair. I wouldn't be surprised to see the Chiefs make a move in the 2nd round, though, if he's still on the board.
