Retired NBA marksman Ray Allen says he would have returned to the Celtics in 2016 if the team had landed Kevin Durant, according to a report from Darren Hartwell of NBC Sports.

Allen spent five seasons with the Celtics (2007-2012), knocking down several big shots along the way. According to NBC's report, the former No. 5 overall pick had a conversation with general manager Danny Ainge in 2016, noting that he would be open to rejoining the team if they were able to secure Durant in free agency.

“I had a conversation with (Ainge) and I told him this was my last-ditch effort. I would’ve went back,” Allen said on WEEI's “Ordway, Merloni & Fauria” radio show.

“This was when Kevin Durant was a free agent. He was thinking about going to Boston. And I said, ‘Hey, if you guys land Kevin, I would certainly look at lacing them back up one more time and try to make something good happen here in Boston.'”

At that time, Allen hadn't played for two season — not since his 2014 stint with the Miami Heat. He would've served as a fine role player alongside Durant, but the Celtics were unable to land him. Had this idea come to fruition, though, Boston would have certainly been a formidable side.

In the end, it seems Celtics fans are left to think of what might have been.
