I guess it pays to be a bit of a playoff hero. Leighton, he of the save career save percentage as Vesa Toskala, just got a contract about three times bigger than players with similar talent. Here are rankings of goaltender save percentage over the last ten years; Leighton is 72nd. Among 51 goaltenders who were active in 2009-10, he's 47th.
Basically, goalies with Leighton's established talent level make $500k a year. Philly overpaid for no good reason.
