Very True, but JT Miller is also an asset to a team, but not someone you build your offense around. Over last season and this one (91 games), Miller is 81st in the NHL in 5v5 scoring.
Over that same stretch, at 5v5 Among forwards with more than 700 min TOI:
- His point total is 77th in the NHL
- His goal total is 145th in the NHL
- his CF% is 231st in the NHL
- his GF% is 161st in the NHL
- his xGF% is 245th in the NHL
Clearly the team and system come into play on those stats to some extent (particularly possession stats), so they are by no means a "be all, end all", but where Miller has excelled last season and this seasons is the PP where he is 8th in the NHL in scoring (for forwards with over 200 min TOI on the PP).
He's definitely an asset to a team. He can play wing or C. He's got size. He is definitely a weapon on the PP, but he's not someone you would build your offense around either, which is fine, because the type of team acquiring him isn't looking to build their offense around him. They are looking at him as a complementary piece to hopefully push them over the top.
