I think the guy could be great but I’m always wary of hiring a HC because of how he used players that he no longer has and aren’t easy to find. Example, Saleh who no longer has Nick Bosa et al and his defense was putrid and he seemed married to his scheme with less talent.
I think the Fish do have some talent at WR but they have a ways to go at RB, TE and OL. Overall if they are going to completely devote themselves to propping up Tua I’ll absolutely take that as a Bills fan. Essentially they are chasing 2nd place in the AFC East and a WC berth as a ceiling.
