Have to say I'm coming around to your opinion on this, if it were up to me we'd have shipped him to anaheim for Fowler before the season started. Good call.
That wouldn't have been the worst move. Fowler is still a stud. Green playing up to expectations and Sproul actually playing the PP point competently has made us forget a bit of our woes on defense.
I'm actually surprised how quickly Mantha has adapted. He's only played 8 games this season and it feels like he's had dozens of memorable shifts. As a big guy, and with the broken leg, I thought it'd take him a full season to make the impact that he's making now.
Its a shame Mantha wasn't brought up as a center. His puck possession/protection, vision and awareness makes me think he would've made a good center at this level. Ignoring the inversion of the tendency to pass versus shoot, something about his game reminds me of Getzlaf or even Thornton (although obviously not as naturally gifted as the latter and possibly the former). I think its the combination of size, fluid skating, and deftness bound up in a very self-assured presence.
