It's a sad day Monday in Philadelphia, as 76ers legend and Hall of Famer Hal Greer has passed away Monday morning at the age of 81.

As if the Sixers needed more otherworldly motivation to go on a title run this season, am I right?

Greer, a true ambassador of the sport, spent 15 seasons in the NBA with the Syracuse Nationals from 1958-63 and the 76ers from 1963-73. A 10-time All-Star drafted out of Marshall, the 6-2 Huntington, West Virginia native was a big part of leading the Sixers to their 1966-67 NBA title victory alongside the great Wilt Chamberlain.

Some of his long list of accolades and accomplishments still stand today. No. 15 was the first one to have his jersey retired by the organization, and he is still the all-time leader in points, field goals, field goals attempted, games and minutes played for the franchise.

Though he was never a physically towering presence, his game was absolutely monstrous. Always a reliable free-throw shooter with a devastating mid-range game, Greer averaged a remarkable 18-to-24 points per game from 1961-71.

The 76ers released a statement shortly after the sad loss.

His 21,586 total career points and 1968 All-Star Game MVP honors are just a part of the reason a statue of Greer resides outside the team's training facilities. 

The 76ers plan to host a commemorative moment to honor the legend and his incredible legacy during Monday night's Game 2 matchup against the Miami Heat at home, a series in which Philly currently holds a 1-0 lead.
