Deadhead is hitting an all-time personal low for bad posting in defending the demotion of Frost. As in, this is actively worse than him defending Hakstol, Hextall, "had no choice" stuff and his constant Konency bashing.
Keep that in mind and carry on.
I'm sorry, I didn't realize that Frost was dominating play when he was sent down.
Silly me, I didn't realize he was a budding superstar!
xGA/60 of 2.58 is well behind all of the top 9 forwards and up there with Andreoff and Vorobyev.
xGF/60 of 2.45 is pretty good, 5th among forwards.
1.67 pp/60 was 8th among forwards, just behind Farabee and just ahead of Pitlick.
CFrel -0.51, xGFrel -1.95
Of course, he had highly sheltered minutes and a high rate of O-zones starts.
O-zone starts per 60 was second to Giroux, D-zone starts one of the lowest at 4.46, compare to say Farabee at 7.74, Hayes at 11.04, or Couts at 11.80 and Laughton at 11.96 [Bunnaman was also highly sheltered at 4.41]
All in all, Frost has played like a so-so 3C this season, and there is no reason to expect that his play will improve as games get more physical and windows get smaller.
Whether you play him or Grant at 3C is a matter of what the coach wants out of his 3rd line.
Thompson didn't put up good metrics in Montreal, but one reason is a D-zone start rate of 15.86/60.
Derek Grant in Anaheim had a D-zone start rate of 19.22/60.
