Legendary clutch shooter is retiring for good after attempted NBA comeback falls short

It was a great run.

Ray Allen gave us some great moments in his 18-year career including bringing Boston its 16th NBA Championship with Kevin Garnett and Paul Pierce. He had many moments as the go-to guy in Milwaukee and Seattle, just gunning the ball in hopes he could do enough to help those teams win.

RELATED: Ray Allen reportedly has just one reason for making an NBA comeback, and it's not to win a title

He joined the Celtics to get that elusive championship ring and he got it. He then became the grizzled vet who could help a team in the locker room and off the bench. He hit "The Shot" against San Antonio in 2013 to absolutely devastate them and lead the Heat to a championship after being down 3-2 in the series.

Allen has been rumored several times to be attempting an NBA comeback, but those efforts fell short. The all-time leader in three-pointers made with 2,973 will officially call it quits and said so in a post with The Players' TribuneHe tells a touching story about his childhood and gives us a glimpse at what made him so great.
