This is where patience can be rewarding. I've said before that I've been hesitant with any desire to move Wood because he has such a unique skillset that if he ever figured it out, he could really click.
I think a couple of things are at play with his success so far in these 3 games. One, I think he is taking it to heart that he needed to mature with the state of the current team. He seems to be recognizing he needs to be more of a leader out there and not play with such reckless abandon as he previously did. While he still has been to a degree, he appears to be more cognizant of when to bring it and when to harness it. It's almost like that first game really opened his eyes with those penalties and that he is applying it going forward.
Secondly, I think it can't be understated how much Travis Zajac relieves pressure from his linemates. He seriously will never get the appreciation that he deserves. He is the most reliable player in every facet, does all the little things no one notices and his linemates tend to be the ones who reap the rewards. Not to discredit Wood at all, but man, Zajac has done this now for how long? Coleman, Noesen, Wood, Gusev. They've all benefitted from being Travis Zajac's wingers.
