Walker is above team averages without MacD, far below with him
Walker without Macdermid: ~188 minutes, slightly harder zone starts, 0.60 CF%rel, -6.27 GF%rel, 1.92 GF/60, 2.87 GA/60
Walker attached to MacDermid: ~118 minutes, slightly safer zones, -5.22 CF%rel, -12.67 GF%rel, 2.55 GF/60, 5.11 GA/60
He hasn't been as good this year as last year, but he also didn't get his face blown up last year and the MacDermid effect is awful.
IMO he's a good Alec Martinez type--a GREAT #5, a GOOD 2nd pairing guy, can matinee on the top pairing if needed.
