Miami Heat icon Udonis Haslem says the franchise has Ray Allen's back, unlike the Boston Celtics.

Allen won his first championship with the Celtics and his second one with the Heat after leaving Boston for Miami in free agency.

Ever since Allen left the Celtics for the Heat, Rajon Rondo and Kevin Garnett haven't been friends with the sharpshooter:

Allen was a three-time NBA All-Star as a member of the Celtics, but his departure to Miami as a free agent after the 2012 season “will have some impact” on the decision to raise his No. 20 to the TD Garden rafters, according to Celtics president of basketball operations Danny Ainge.

Gordon Hayward has worn No. 20 since he signed with the Celtics in 2017. He is the only Celtics player to wear the No. 20 since Allen left.

Allen appeared in 152 games for the Heat during the regular season. He averaged 10.3 points. Of course, all Heat — and basketball fans for that matter — will remember Allen's game-tying 3 against the San Antonio Spurs in Game 6 of the 2013 Finals. Without that shot, the Heat don't win the championship.

Allen was voted in as a Hall of Famer last season. He will go down as one of the best shooters in NBA history.

If not for Golden State Warriors star point guard Stephen Curry, we would probably still call Ray Allen the greatest shooter of all time.
