In an appearance on FS1’s Undisputed, longtime Pittsburgh Steeler and 2017 New England Patriot, James Harrison, confirmed to host Skip Bayless that Bill Belichick is a better coach than Mike Tomlin. By far.

In fact, Bayless had hardly finished asking the question when the former linebacker gave his answer. He didn’t hesitate for a moment.

“Mike Tomlin is good as a head coach. He’s a player’s head coach. I think he needs to be a little bit more disciplined,” said Harrison. “The big thing with Belichick is he’s very regimented, he’s disciplined, everyone is going to be on the same page. There’s not going to be anything as far as someone doing there thing. And I think over there, their whole coaching staff is like that.”

Harrison notably hit the ground running with the Patriots, a team he’d admittedly hated for a long time because of their AFC rivalry. After being released late in the season and picked up by New England, he recorded 2.0 sacks and five tackles in his only regular season game with the Patriots, and went on to become a consistent presence on the field throughout their postseason run to Super Bowl LII.

“I ain’t never been to so many meetings in my life. And I think that’s really what helped me pick up that defense so fast,” he said in regards to Belichick’s approach to team preparation.

Harrison also harped on Tomlin’s issues with consistency in the way he dealt with his players, crediting Belichick with holding every player to the same team-wide standards.

“I think it’s easier if you hold everyone accountable because you don’t have to treat anyone differently because of a certain situation or a certain player,” he said. “It’s a lot easier across the board. It don’t look like you’re playing favorites. “Man, I’ve seen Tom Brady running to a meeting scared to be late. So if you see that, yeah. I don’t even know what happens if you’re late to a meeting over there!”

While he was only with the team for just over a month in an official capacity, he found playing for the notoriously tough Belichick to be perfect for him personally.

“Playing for him is easy. If you’re used to regiment, used to discipline, it’s not something that’s hard to do,” Harrison explained. “If you’re not, then you’re going to have some issues until you get in line. “It was actually fun. He’s nothing like the guy that you see on a TV. He just told me straight up, ‘You know I see you doing this here, if you do that well, it’s a possibility that it could grow.’ And as the weeks went on, I got more and more snaps.”

It should be noted that Harrison left the Steelers with a bad taste in his mouth, so he doesn’t have a ton of incentive to take Tomlin’s side in such a conversation. Still, the evidence of Belichick’s superiority as a head coach is just about everywhere — from his five Super Bowl rings, to his 7-2 record against Tomlin head-to-head, to the fact that his players keep locker room drama insulated from constantly inquiring minds.

Harrison obviously made an instant connection with Belichick, and it’s clear that the organization he’d spent most of his career hating quickly earned his respect. I have no evidence that this is even on the table, but let’s just say I wouldn’t be surprised to see a coaching position on the New England sideline in his future.
