The more i look at Cozens advanced stats, the more i think that maybe he's more of an energy third line winger, rather than an actual top six C.
his 31 goal year seems like it was an anomaly, super high shooting percentage that one year while all the other years he shoots at only 9%, like, VERY consistently at 9ish percent... when you only put 200 - 225 shots on goal at 9 percent you got a 20 - 23 goal guy (ish).
He's not great at the faceoffs and doesnt seem to produce even though he has strong 5on5 corsi (relative to team mates) , oddly, the one year he scored 31, he had horrible corsi numbers... which makes me think he was used as a triggerman.
he's still really young so who knows, maybe he has a Necas like trajectory in the next 2 - 3 years.... both fast, taller, good frame players who were drafted as C's but play Wing...they're also both primarily north-south type players.
