I'd support that. I also think Cook has the ability to carry the ball more (similar to Singletary maybe?) than Hines. Agree that both need to improve the pass protection.
Here's a little roto/fantasy writeup on Cook
While not exactly fantasy relevant outside deep fantasy formats, Cook was quite good as a rookie. On 89 rushing attempts in a split Buffalo backfield, Cook had an elite yards before contact per carry of 3, second among all qualifying backs. He was 19th in yards after contact per carry (2.7) and led the league in PFF's breakaway rate (44.1 percent).
Cook acquitted himself well as a pass catcher too. Only nine running backs who saw at least 30 targets in 2022 had a higher yards per route run than Cook (1.7). We could see him take that role for himself with the Bills' signing of early-down banger Damien Harris, a move that should keep Cook's redraft ADP nice and suppressed throughout the spring and summer. Cook was never going to see a massive workload in the Buffalo offense. His best-case scenario -- lead back duties on a potent Buffalo offense -- and his rookie year efficiency give Cook plenty of appeal at what should be a reasonable ADP.
And yes - I'm dumn, it's Singletary, not Singleton.
