the Byron contract seems a bit long but really he has 8 goals in 45 games. That's amazing for a 4th liner. A 4th liner with 10 goals all year is great and we haven't seem to have one in a long time. He's got close to that in a half season. I'm totally fine with the Byron contract.
He's not a 4th liner though. He plays 13:38 minutes a game. He's 10th among forwards for the total TOI but he'll catch up Weise soon so he'll end the season as one of the 9 most used forwards. 8 goals for a borderline 3rd line player is nothing to write home about. Specially when he is shooting for 20%.
He plays a lot in PK but the thing is around 40% of his production comes from the pk. 37.5% of his goals come from the pk. 38.4% of his points come from the pk. That's imo not sustainable long term.
He is the 10th most used forward at ES. Again he'll catch up Weise soon so he'll finish the season as one of the 9 most used forwards at ES. His ES production is 5 goals and 8 points. That's actually kind of bad for someone playing 11:37 at ES every game. That's goon like production. In fact Shawn Thornton did better than that some seasons.
Until proved otherwise the next seasons Byron's season (the goals part) is a statistical fluke. His shooting % is way higher than normal. He's pk production too. He's been bad lately. He has 2 points (2 assists) -7 in his last 15 games despite playing mostly on the 2nd line with Plekenec. His TOI in the last 15 games is around 15 minutes.
We don't know what he will do while used purely on a 4th line (we will probably never know it with MT). A lot of his points and goals this season came from the pk. He wont continue to shot for 20% and produce so much in the pk. Other teams will adjust. His production at ES had been close to abyssal considering his usage. I really don't see what people see in this player. His production at ES is close to a goon. He plays more than a goon. Outside of the pk he's a black hole.
