Whether it’s Gerald Green ‘s glorious return to the NBA, the sight of Semih Erden facing them as a starting center or the team’s woeful offensive production, a number of factors led me to this question: When is the last time Celtics  president Danny Ainge or coach Doc Rivers  has either drafted or developed a scorer?
Clearly, Rajon Rondo  is the best player cultivated under the Ainge-Rivers regime, but I don’t think anybody would argue Rondo has markedly improved in the scoring department. His scoring averages per 36 minutes in his rookie season (9.9 points) and last season (10.3) are nearly identical, and we all know about that jump shot.
The best scorer drafted by Ainge has to be Al Jefferson , but even his 36-minute averages didn’t improve much under Rivers, crawling from 16.3 as a rookie to 17.2 in his final Celtics season. Not until he was traded to the Timberwolves  did those averages climb into the 20s. Of course Ainge and Rivers deserve credit for molding Big Al into bait to land Kevin Garnett , but the fact remains Jefferson made a leap offensively once he left the Celtics.
The same goes for Tony Allen , Ryan Gomes , Leon Powe  and Bill Walker , all of whose 36-minute scoring averages barely budged in either direction on the Celtics, and then saw those numbers rise once they left Boston.
Ainge probably deserves the blame for drafting Justin Reed, Orien Greene, Gabe Pruitt , J.R. Giddens, Lester Hudson  and even Green, all of whom never hung on in the NBA regardless of who was coaching them. You can probably add Luke Harangody (he of the 25.0 FG%) to that list fairly soon as well.
Delonte West  and Glen Davis  had flashes of brilliance in Celtics uniforms, establishing themselves as certifiable NBA players. Still, would you say either West or Davis improved as scorers in Boston? Sure, their point totals rose as a result of more field goal attempts, but did their reliability as scorers change from Season 1 to Season 3 or 4?
Last year’s rookies, Erden and Avery Bradley , are yet to be determined. Erden didn’t have time to improve on the Celtics, as Ainge shipped him to Cleveland along with Harangody for a second-round pick, but the Turkish terror has shown signs of improvement since entering the Cavaliers  starting lineup seven games ago (i.e., 18 points on 7-of-8 shooting in a victory against the Pacers two weeks ago).
And find me somebody who thinks Bradley has developed his scoring game since his arrival in Boston.
That leaves JaJuan Johnson  and E’Twaun Moore , both of whom established themselves as collegiate scorers and have illustrated that ability in stints as NBA rookies. Johnson and Moore are respectively averaging 15.9 and 11.3 points per 36 minutes, but the question remains: Will they develop into consistent scorers for the Celtics?
Not if history has anything to do with it. We’ll let these 36-minute scoring averages drive that point home.
