On Monday, the NFL was stunned by the trading of Pro Bowl linebacker Jamie Collins.

Collins was sent by the New England Patriots to the Cleveland Browns for a third-round compensatory draft pick. Apparently, Collins wanted “Von Miller” money in his new contract next season, and the Patriots weren't going to comply.

The only person sadder than Collins, who goes from a 7-1 Super Bowl contender to the only windless team left in the NFL, might by Tom Brady.

Throughout Brady's 17-year tenure with the Patriots, he's seen a number of key contributors depart. From Lawyer Milloy, to Mike Vrabel, to Chandler Jones this past offseason, Brady is always sad to say goodbye.

From ESPN's Mike Reiss:

“It’s always tough to hear news like that with a teammate that I’ve played with and been in so many battles with. Jamie is a great player for our team and I’m sure he’ll be a great player for the Cleveland Browns,” Brady said during his weekly appearance on Westwood One Radio.

“I’m always sad when we lose a player that I like and someone that I respect like Jamie. It’s a tough day, but it’s part of the NFL, this business. Coach Belichick makes these decisions and we as players still have to go out and do our job. That’s enough of a challenge as it is. We’re in a bye week now, we’re at 7-1 so we’re in a decent place, and we have our whole season ahead of us.”

“When there’s players that are coming, it’s very exciting. And then when you lose players, it’s obviously very disappointing because you have relationships with those players that you’ve really worked hard to build,” Brady said on Westwood One. “I loved playing with Jamie, I loved seeing him out on the field. He’s moving on to a different place, a different environment for him. The makeup of our team will be different and hopefully the guys that fill in for him now will do a great job for us.”
