Whenever Bill Belichick decides to retire, it will be based on how feels, not how many rings he's acquired.
That's what former Patriots coaching assistant Michael Lombardi told WEEI's Dennis and Callahan Show with Kirk Minihane, Gerry Callahan and Gary Tanguay on Friday.
"I think he likes it," Lombardi said of Belichick, 64. "I think he's really good at his job. I think he likes his job. I think he has a passion for his job. There's no coach in the NFL today that works harder than Bill Belichick. No one . . .
"I think it's a hobby and it's also a profession. When you combine those two together, he's never going to work. He enjoys it. I think when he gets away, he gets away, which is something early in his career perhaps he didn't do. He was always kind of 'on.' But now I think he can get away, he can rest, he can relax, and I think he rejuvenates himself to where he can come back. I don't know how long he's going to do it, but I know this, it's not measured by wins, it's not measured by Super Bowls, it's going to be measured by how he feels."
Lombardi said he and the Patriots parted ways in June because he was focused on getting back into a career in the media.
"It was a decision on my part to move forward into my career," he said. "At this point, after my contract with the Browns had expired, it was time for me to make a decision on what I wanted to do for the next 10 years . . . I'd love to stay at the Patriots, and Bill and I have a great working relationship. Until this day we still have a great working relationship. However I thought it was time for me to go into another career. I really want to write a book and that's what I've been working on.
Lombardi has had a varied career in the NFL, which has spanned over 30 years. He said that his book would delve into his unique experiences as someone who has worked under Belichick, Bill Walsh and Al Davis.
"I don't know if anybody's worked for the three of them, and for an extended period time, which I have," Lombardi said. "And I think that needs to be put on paper."
