12 year average RAPM data<\/a>.\u00a0 Since so many years are used, it is quite stable; however, one simply gets an “average” view of the players.<\/p>\nIt is wonderful, though, for looking at broad trends–and perfect for looking at replacement level.\u00a0 Remember–RAPM will regress all players toward a uniform prior, so for very-low-minutes players, the results are biased toward that value.\u00a0 However, once, say, 1500 minutes are played, the results stop being biased toward the prior significantly.\u00a0 This is visible in the graphic below.<\/p>\n
So what is replacement level?\u00a0 I would define it as a player that can easily be obtained at a minimum salary.\u00a0 This likely would mean playing only some games (perhaps 30-40) at 8 or so minutes per game.<\/p>\n
Using RAPM, we can identify a fairly linear relationship between MPG and RAPM performance, and thus derive an estimated replacement level for RAPM.<\/p>\n
In this case, I would estimate replacement level at about -3.35 for overall, -2.65 for offense, and -0.70 for defense.<\/p>\n
