I don't think we'll see both PTO players (Gagne & Leino) make the roster. I think it'll only be one and I think Gagne is a better fit... if he's healed, could be a diamond.
Leino was a top 40 Selke nominee several years back, had a couple of PO's where he was over a point per game pace (or close to it, iirc).
But he sucks on the FO (around 45% last year, less than 200 draws), so if the B's were to jettison Kelly, it's not a great replacement - but he has had success preventing goals and, defensively, I think he could be a better fit than Caron... but many players are better fits than Caron.
If Leino does beat out some of the kids... well then that speaks plenty more towards the B's poor drafting choices and, imo, reinforces why Sweeney is now really watching Cassidy in Providence.
Ideally, should we even be having this conversation? No, we shouldn't. There should be better options and/or the kids should be clearly heads and toes so good/ready to make an impact that PC wouldn't have even entertained the idea to invite Leino.
Let's see how this shakes out at camp.
