Some context is needed here. McTavish is earlier in his development than Byram.
Byram was drafted in 2019 and McTavish was drafted in 2021. So, last year was McTavish’s 1st year in the NHL, and this was Byram’s 3rd.
Byram also played 7 more minutes per game than McTavish this year. That’s significant. Naturally he’s going to get more opportunity within that.
You’re talking about Byram needing more opportunity, but he had a lot more than McTavish. He barely played with Zegras. I think you look at a 43 point season playing basically 3rd line minutes, that’s pretty damn good.
I think there’s room for growth in both players games, but probably more with McTavish, especially on a second line with Rantanen.
This is missing some important context as well though Northern.
Bo's only 1.5 years older than McTavsh, and he's only played 2 more regular season NHL games than him. Yes two. So I don't see a big difference in their development time. Going off seasons is pretty misleading, since Bo has barely played in those seasons.
If you want to go off last season's production, Bo paced for a very similar 14 goals and 46 points to his 20 goal 47 point pace this year, while playing an even lesser role mostly on the third pair, with even less PP time, compared to McTavish's 17 goal 44 point pace this year.
As for role, whatever role McTavish had, it wasn't that much smaller than Bo's on defense playing on the second pair this year, getting about a 20 second PP2 shift at the end of the power play.
Meanwhile, McTavish played on PP1 and averaged 1:19 more than Bo this year. 33% of McTavish's points came on the PP, while only 25% of Bo's did. Season before only 6% of Bo's points came on the PP with 1 point.
All of that means there's a good chance Bo will produce at an even higher pace, if given a bigger role on the team as expected.
Bo is also a defenseman not a forward, so the overall TOI comparison is apples to oranges. Defenseman play more anyway, and forwards spend most of their shift trying to score, while defenseman spend most of their shift defending.
This is also why it's meaningful when a defenseman outscores or outpaces a forward in both goals and points.
That may not stay the same if McTavish gets better, but 21 year old 20+ goal 50+ point, two way, top pairing capable defenseman like Bo clearly is don't grow on trees, and they should NEVER be traded to fill a 2C role. Nor do they need to, in order to acquire one.
