Reed, who agreed in principle last week to become the Bills' assistant defensive backs coach next season, explained it all to Showtime's "Inside the NFL" on Tuesday night.
"I was making some nachos for my son, man," Reed, a regular guest analyst on the program, said. "Some turkey nachos. I saw the phone ringing and it said, 'Rex Ryan.' I was like, 'Whoa, Rex Ryan, what's going on?' And he's like, 'Eddddy Reeeed!' He's like, 'How would you like to come coach?'
"I was like, 'I wouldn't mind it, Coach, I'll think about that.' He was like -- we started talking some football talk and I told him I would get back to him. [I said] 'I'd have to talk to my son and his mother about the transition if I was going to make that and how would that fare with the family and everything.' And he was like, 'OK, take your time, I'll call you back this weekend.'
"Well two days later -- it wasn't the weekend -- he called me and he was like, 'So what you thinking?' My son, he wasn't for it at first. He's actually a Patriots fan. So I was like, 'Coach, we got to sell my son a little bit more, man. You got to get him some gear.' And he was like, 'He can get whatever he wants.'"
The longtime Baltimore Ravens ballhawk retired last May after 12 NFL seasons, including three playoff appearances against Tom Brady and the New England Patriots. Asked on Twitter earlier Tuesday about how to beat Brady and the Patriots, Reed responded in a video simply with, "Pray."
Ryan, of course, can relate. He has spent the past seven seasons as a head coach in the AFC East and he spent the four years prior (2005-2008) as Reed's defensive coordinator in Baltimore. While Ryan has experienced some success against Brady, he has never come out on top of the Patriots in the division.
Now Reed and Ryan will join forces this season to try to make that happen -- even if Reed's son begrudgingly dons a different shade of blue and red.
Reed recognizes that there will be a learning curve as he transitions into a possible career in coaching.
"You just have to be able to relate to guys. Relate to players, relate to the person," Reed said. "I've been running my football camp for 14 years and coaching kids, and trying to help kids out. I mentored a bunch of guys on every level: high school, college and pros. So I think I've already been a coach, for that matter.
"Yeah, it's gonna take some learning to be a coach. And that takes coaching. I mean, the head coach's job is to coach the coaches, to coach the players. So I'm looking forward to learning, but at the same time, I won't forget that I've learned over time."
