I didn't listen to the interview but if people are suggesting that because Allen is elite that the focus should be on the Defense then you are entirely wrong.
The Bills have spent numerous picks on Defense that have resulted in the lackluster Defense the Bills have now. If you focus on the Offense and make your strength stronger you can create an unstoppable Offense with Allen. I look at the Chiefs with Hill/Kelce and just their ability to score 30+ in every playoff game and put pressure on their opponents Offense to keep up. During the regular season this happens but when the playoffs come you saw an Offense that struggled against the Ravens and had a chance to go up 2 scores late against the Chiefs and failed. The Bills Offense needs to be an elite WR that allows Allen to utilize his other targets and legs. Instead teams can go man and spy Allen and focus on stopping the run game.
