A look at some noteworthy numbers before the Celtics host the Hawks in Game 3 of an Eastern Conference quarterfinal series at TD Garden, as researched by our friends at Elias Sports Bureau:
* Celtics rookie center Greg Stiemsma is averaging 21.3 rebounds per 48 minutes in this year’s playoffs. Only one player is averaging more rebounds per 48 minutes than Stiemsma in the postseason (minimum 25 minutes): Utah’s Enes Kanter (24.0).
* Sure, the Celtics missed their first 19 3-pointers of the series, but one Hawk has his own dubious trifecta streak: Josh Smith has missed each of his last 13 attempts from 3-point range in the playoffs dating back to last year’s postseason. That is tied with the Lakers’ Matt Barnes for most consecutive 3-pointers missed among players who have appeared in a game in the 2012 playoffs.
* The Hawks are shooting only 29.3 percent from the field in the second half in this series. There are seven players that have made 25 percent or less of their second-half field-goal attempts in the playoffs (min: 10 attempts) and three of them are on Atlanta: Joe Johnson (3-for-16, .188), Josh Smith (4-for-18, .222) and Jeff Teague (3-for-12, .250). The others are Jason Kidd (2-for-17, .118), Shane Battier (2-for-11, .182), Vince Carter (3-for-14, .214) and Landry Fields (3-for-12, .250).
* Paul Pierce registered 36 points and 14 rebounds in Boston’s Game 2 victory on Tuesday night. Only two other players in Boston’s franchise history have recorded at least 35 points and 14 rebounds in a playoff game: Tom Heinsohn did it twice (April 13, 1957 and April 19, 1963) and Dave Cowens (April 24, 1977).
* The Celtics have won nine of the 10 playoff series played between these two teams, with the Hawks only series victory against Boston coming in the 1958 NBA Finals while the team was located in St. Louis. Boston’s .900 winning percentage in playoff series against the Hawks is the highest any team has over another in NBA history (minimum: six series played).
* Tracy McGrady has played 40 career playoff games, and all have taken place in the first round. That is the second-most career playoff games for any player that made his NBA debut in the 1983-84 season or later (the year the current playoff format was instituted) and has never appeared in a game beyond the first round, trailing only Andre Miller (41).
* The Celtics have scored fewer than 100 points in each of the last 14 playoff games they have played at home, the longest streak of its kind in Boston’s postseason history (previous long: seven straight in 2008). Only one team has a longer current streak of consecutive home playoff games with fewer than 100 points than Boston: New York (26 straight).
