#3: Bill Sharman
Bill Sharman was an excellent shooting guard for the Boston Celtics, posting career numbers of 17.8 points 3 assists, and 3.9 rebounds per game. It's unknown how many steals or blocks Sharman recorded because they didn't keep track of those stats back then, but he was a good defender and is estimated to have around 1.5 steals per game. Sharman was one of the best free throw shooters ever, leading the league in that category 7 times and being 11th all time in free throw percentage.
#2: Sam Jones
Jones, one of the best shooters in Celtics history, is known for his clutch shooting and unstoppable bank shot. He led the team in scoring three times and played all 12 of his seasons in Boston. He's the seventh best scorer in Boston Celtics history, with 15, 411 career points. Sam Jones played with Bill Russell and won 10 NBA titles.
#1: John Havlicek
This choice is controversial because Havlicek is more of a small forward than a shooting guard. Nonetheless, Hondo is the best SG in Celtics history because if he played today, he would be a shooting guard. The 6'5 sharpshooter has played the most minutes in Boston Celtics history, has made the most field goals, and is second in assists. His career numbers are astounding: 20.8 points, 4.8 assists, and 6.3 rebounds per game. Havlicek won 8 NBA Championships, including 4 in his first 4 seasons. Hondo spent all 16 of his NBA seasons with the greatest NBA Franchise in the history.
