That his game hasn't matured much season by season over the last 3.
By comparison Bratts game from year 2 to year 5 is much much smarter and sounder. He is also physically much more attuned to the rigors. You can see Bratts growth/maturity in his game season to season. 2 seasons ago right before the surge streak Bratt was being yelled at by me / us for all his dumbass giveaways. We didn't see that as much last season. In the playoffs we yelled at Bratt for being softish. Last season we saw him go hard into corners a lot more, take/roll off a hit, make the hard play.
Jack's game kinda looks like the same game he had in his 2nd year.
I said earlier (some threads ago) that I'll try not to judge until 10-12 games in, so yeah it's only 3 games, but the trend extends to last season. But of all the players on this team, I'm concerned about Jack's overall game. Nico, Timo, Bratt look like themselves (and good versions), Dougie for the most part, too. Tatar as we expected.
Mercer hard to say yet but generally fits into his like as expected past, Palat is flat, so is Haula (but his game is trending up a bit). 4th line is looking normal-ish.
