I may be in the minority, but I don't see Mantha as (or want him to be) a "net front" guy. I think that would ruin him. He's got the skill, shot, and speed to be a power sniper type guy in the vein of Rick Nash, James Neal, or Blake Wheeler. Let guys like Abby bang and crash in front of the net. That takes almost no skill. I want Mantha to have more freedom than that.
Similarly, I think that's one of the problems with Jurco. He's big, so everybody wants him to play a power game. But that's not his forte. He's more comparable to Nyquist or Tatar than he is to Abby. But they keep trying to make him be that guy and it's awkward for him because he's never played that way. Reminds me a little of how they used to want Filppula to "shoot more" so they put him on the wing. It was always going to be a bad fit for him.
Imagine if someone had repeatedly beat into Marian Hossa, or Nash, or any number of other guys, that they needed to play "heavy" and crash the net, and look for shot tips and rebounds. They'd have been wasted.
