To me the biggest question mark is Rochell. I thought he would end up seeing significant snaps as, at worst, the CB3 or CB4. he had 17 defensive snaps the first 5 games and just one since. He's a nice ST player (4th most on the team) but should be more by now. 2023 is a big year for him and I think he's someone that will not be guaranteed a roster spot ($767k saved if released).
But with the rookies, honestly, I can't see anything to complain about right now. Durant played pretty well vs. ATL early on before his injury and has played a lot of ST in the 5 games since he's been back. Kendrick has held his own for a rookie 6th rounder. Lake was out all summer and through October with his injury and is just now being activated (46 ST snaps the past three games).
They absolutely need those three to elevate their games in 2023 for sure (with Hill, Long, Scott and Rapp all free agents; I'd love to have Scott back personally).
Also disappointing that Fuller is now 8 weeks from his hamstring injury and still not back yet.
