Miller's put up some good defensive numbers.
His most common defensive partners over the last 3 seasons at 5v5:
720:46 with Heiskanen in DAL: 2.29 xGA/60.
350:32 with Bryson in BUF: 2.43 xGA/60
288:49 with Hughes in NJ: 2.67 xGA/60
228:38 with Suter in DAL: 2.51 xGA/60
Overall his on-ice numbers at 5v5 over the last 3 seasons (vs all defensemen >1000 TOI):
xGA/60: 2.38 (tied for 49th out of 234 - Top Jets: Samberg 2.32, 29th ; DeMelo 2.47, 82nd)
GF - GA: 121-86 (+35, 58.45% -11th best - Top Jets: Samberg 68-48 +20 58.62%, DeMelo 151-122 +29, 55.31%, Morrissey 193-156 +37 55.30%).
I hope he's not one of these guys whose team massively outscores opponents when he's on the ice but they lose the game anyway like that Ehlers guy!
