He’s also on the OL… he also will be asked to catch ball from a QB that puts heat on the ball. He’ll be in piles…. You ever go to block or tackle in a game and you hand gets smashed? Buying time is just insurance, but in the meantime you add a whole other dimension with possibly Knox and Engram together.
Im sure the Bills want home field advantage. IMO when chasing a potential championship and your TE requires hand surgery…. I think it may be worth a 5th if that’s the going price. I see Knox back week 11 vs Indy, but I also bet he won’t be a huge part of the game plan for risk reasons.
