ThisBengals coaches speak up on loss at BillsOn Monday, Bengals head coach Zac Taylor addressed the loss at the Bills. One of the things he addressed was the defense's struggle to contain tight ends Dawson Knox, Dalton Kincaid, and Jackson Hawes, who together accounted for two of Josh Allen's passing touchdowns and over half of his passing yards:“I know (defensive coordinator) Al (Golden)’s trying to help them schematically as well. So each one’s a little bit of its a unique look because you might be in a different coverage, it might be a different look. Might be a different way that they got the tight end there. But certainly has been something that’s bit us and we’ve got to work like crazy to rectify it.”He continued:“It’s hand in hand if you played a team who’s first in the league in rushing, so how are you going to stop that? You got to commit to stopping it, and at times, it’s going to free up some guys behind you.”Speaking of Al Golden, he was adamant that this performance was in no way a reversal from what his unit had been doing in the previous three games. Nevertheless, he had a stern message:“We've got to eliminate the plays that are hurting us.”The Bengals' next game will be at the Miami Dolphins on Sunday. Kickoff is at 1 pm ET on CBS.
