Well he played 14 games... last season he paced 34.
Well he now has a sample size of like 5 years in the league and he doesn't ever meet expectations. He's always injured, or not producing, or whatever.
At some point the player is what he is. He'll eventually produce an outlier season of 30 points or so at age 28 and everyone will say "See, this is what he is!" and then he'll regress the following season because any little thing not coming up Blais is enough to sink his production. It's the hallmark of a player who should be deployed in a lower setting.
I like him on the fourth line.
But with what we have in hand I don't want him as a third liner on this roster next year. Without a single addition I like
Lafreniere - Zibanejad - Kreider
Panarin - Copp - Kakko
Goodrow - Chytil - Kravtsov
better than putting Blais on the third line.
And if we can add another player to that top 9 (ie, Othmann surprises, we can work some cap magic to keep Vatrano, etc) then Goodrow is moved off first.
But again, it's not to say there's zero value there. I would love a Goodrow-Blais pairing on the fourth line. That matchup dominates other fourth lines and helps you win games consistently.
