FOXBOROUGH, Mass. -- Second-year quarterback Jacoby Brissett's leadership was one of the more impressive qualities he brought to the New England Patriots. Younger players, in particular, seemed to rally around him.

In the wake of Saturday's trade that sent Brissett to the Indianapolis Colts in exchange for receiver Phillip Dorsett, Brissett penned a thank-you note that he shared on Instagram.

To the Patriots organization thank you for the opportunity. The countless memories will live forever. To that locker and the friends/relationships that I've gain in such a short amount of time thank you guys for accepting me. Excited for this new journey in Indy and can't wait to get started. #BloodBrothers.... Letsssss Gooooo A post shared by Jacoby Brissett (@jbrissett7) on Sep 3, 2017 at 5:05am PDT

Brissett's intangibles were widely viewed as impressive by several in the Patriots' organization. He would have added a third layer on the quarterback depth chart this season, which has value (as it did in 2016), but in explaining the trade Sunday morning, coach Bill Belichick said: "If you want to get something, you have to give up something."

In explaining what traits drew the Patriots to Dorsett, Belichick said, "He's a pretty talented player. A first-round draft pick."

Asked what made Dorsett a first-round pick out of Miami in 2015, Belichick said, "He was productive. Fast. Caught the ball well. Made big plays."
