I'm pretty shocked by this. Wonder if they are scouting ahead for him as OC if the Bills don't keep him in the position.
And the same answer comes up every year - there isn't enough time in the calendar to delay it. 4 weeks to shortlist, interview, select a coach. Hire an entire staff. Evaluate your entire roster. Then negotiate contracts with the agents of pending FAs you want to keep. Then evaluate and decide which FAs from outside you want to target.
Can you move free agency back? Sure. Then you have to move the draft back. And then you run out of space for rookie camps before the one month a year
