Andrew Luck’s former teammates aren’t pleased with Colts fans for booing the now-retired quarterback Saturday night as he walked off the field.

“I thought it was bulls–t, simple as that,” center Ryan Kelly told reporters Monday.

Luck’s replacement Jacoby Brissett also didn’t like hearing the boos, particularly because of what Luck has meant to the franchise.

“It sucked,” Brissett said Monday during a press conference. “You don’t want to hear that, especially a guy like that who’s done as much as he’s done and what he’s been through. Even before I got here and talking to him and hearing a lot of those stories, like, nah.”

Brissett found out a day before the rest of the world that the 29-year-old Luck would be retiring. The two have become close friends since the Colts acquired Brissett from the Patriots before the 2017 season. It will be weird, Brissett said, not seeing Luck every day, but he believes Luck made the right decision after speaking with him.

“I was shocked, which I’m sure everybody is,” Brissett said. “And then we had a long conversation, and there were some emotions going back and forth, but when you sit down and you talk to him, you understand his decision. It’s one of my good friends so it’s tough, but I’m sure both of us will deal with it.”

When asked if Luck seemed at peace with retiring after years of physical and mental anguish, Brissett did not hesitate.

“Oh, no question,” Brissett said. “He was like smiling, you know? That’s what helped me gain clarity and understanding of the situation, seeing him smile. I wish him the best. He knows that. We’ll talk longer than the days of either one of our football careers.”

Colts coach Frank Reich, after addressing the team Monday morning with GM Chris Ballard, praised Luck’s decision, saying he “did the courageous thing and the honorable thing” in retiring. He made it clear that he didn’t feel Luck was letting the team down.

“On one hand, we can respect and honor the player and the teammate that Andrew is and was,” Reich said. “But at the same time we can share an excitement and an enthusiasm about the team that we have going forward and the journey ahead of us.”

Brissett started 15 games during that 2017 season when Luck was out following shoulder surgery. The 26-year-old has more experience now and will be playing behind an improved offensive line. Reich and other Colts staffers determined Brissett took roughly 1,200 first-team reps throughout this offseason with Luck nursing his mysterious ankle injury. Reich thinks Brissett can be a top-20 quarterback.

“I’m sure glad we got him now,” Reich said.
