Watching that line, Tippett is the one who drives the line in terms of offensive zone entries, Michkov is the playmaker, Frost at times looks like a third wheel, at times plays aggressively, attacking the net. He is the defensive conscious for that line.
When I watch other "finesse" centers, Frost just isn't as talented either handling the puck or as a playmaker. It's not that he's bad, he's just a cut below them (not McDavid or McKinnon, everyone is a cut below, but the next tier, the 1C/2C types). His speed doesn't translate to the ice as well as it should. He fumbles a lot of pucks. As close to Poehling as to Robert Thomas or Aho.
Centers the last ten games since the lines were put together:
Frost xGF 69.90%, HDCF 66.46%
Cates xGF 66.15%, HDCF 67.97%
Poehling xGF 54.92%, HDCF 57.40%
Couts xGF 49.95%, HDCF 50.65%
Briere has some tough decisions, I think Couts' days as a center are numbered.
Do you just plug Jett in next year, keep Frost, or trade for center(s)?
Even if you draft a couple more, they're 2-3 years away.
