One observation I have made about Brule that worries me slightly is he seems to get an inordinate proportion of his points on the powerplay. He's still very good even strength, but I'd like to see him produce a bit more 5 on 5. Better linemates than a leech in Tim Kraus, a struggling Mitch Bartley, a goon in Triston Grant and a lazy underproducing overager in Ty Morris (these are the guys he's played with for the most part) would probably help in this regard, but it's still something to look at.
I would also disagree that Brule wouldn't make a good NHL checker; on the contrary, I think part of what makes him a great prospect is that if he for some reason doesn't reach his offensive potential, he has a solid fallback option as a good 3rd line player. He's physical, he skates very well, and he has the right competitive spirit and attitude to be a checker. Don't know about Bourret.
Most of Brule's PIMS ARE roughing/fighting/misconducts resulting from fights, but I think it's fair to say that he gets himself in the box a bit too much, regardless of what it's for. But hey, if you want that combination of competitiveness, toughness and a bit of mean streak, you're gonna get some penalties with it. The tradeoff is worth it if you ask me.
