I like AK as the vet RB in the room, especially for Jeanty who is following AK in how he takes care of his body, etc. I prefer AK shift to a Kevin Faulk/James White role or even more as a slot WR. He can run the routes like a WR and he's a lot more sturdy for going across the middle than anyone else we have for the slot. Having him in a hybrid role will extend his career and take advantage of his playmaking ability. It could also allow him to be effective later in the season as we've seen the wear and tear through a seaon makes him less effective and available late in the year.
He likely won't make it as a wide receiver. Corners are far more effective in coverage then linebackers and most safeties which is who usually picks up the RB out of the backfield. It's one thing to occasionally line your RB out wide. It's another to do it always and expect them to beat Corners in coverage. It's one reason why Hamilton is such a hyped up Safety. He can cover like a corner and has single handedly shut down RB's passing games before which allows the Ravens defense to stay in a formation matching CB's to WR's. Where as some teams when facing a pass catching RB will put an extra DB on the field, but a simple audible to a run play by the offense puts that formation at risk.
