The Celtics front office is known for valuing metrics, so it should be no surprise to learn that two of the big moves they made this offseason were lauded by those in the analytics crowd.
Most notably, Boston signed big man Amir Johnson -- a perennial RPM darling -- to a two-year, $24 million contract after Toronto decided they could live without his elite offensive efficiency (60.3 true shooting percentage) and cagey interior defense. On the strength of his sterling +3.90 Predictive RPM, Johnson is expected to generate nearly $16 million in surplus value for the Celts over the next two seasons.
