You can count Richard Seymour as one of many who viewed Tom Brady's decision to leave the New England Patriots as “unexpected.”

Seymour teamed up with Brady for the first eight seasons of his career. Although Seymour played along the defensive line, both played key roles in New England winning their first three Super Bowls.

And just like Seymour, Brady's NFL career will likely end with another team not named the Patriots. That would be because the 42-year-old veteran quarterback made his decision to sign with the Tampa Bay Buccaneers. Needless to say, Brady's former teammate expressed surprise over his former teammate's decision to depart New England.

“I’ll say this, I thought it was unexpected,” Seymour said on the latest episode of NBC Sports Boston’s “The Michael Holley Podcast.” “I didn’t see it happening, but I’ll say this, Tom has earned that right. He’s a guy that’s always looking for new challenges, the ultimate competitor. I thought they would work it out and try to figure out a way to get it done, but it’s a business and he’s earned that right to test the market and see what’s out there and how other organizations are ran, that sort of thing.

“Any time you go somewhere new, it brings out a new challenge — new teammates, new coaches and a new system to learn. … I think he’s going to relish in that opportunity and I wish both of them well.”

For the first time in Brady's 20-year career, he'll play for a team not named the Patriots. As Seymour mentions during the interview, the veteran quarterback is always looking for new challenges. He'll have one big challenge ahead of him as he looks to lead a franchise that hasn't made the playoffs in 13 years.

We'll see if Brady is able to attain some of the same success in Tampa Bay that he achieved in New England with the Patriots.
