I don't think Holland has done anything for the team. I think it's been other people and Holland getting more credit than he deserves. Bowman was still here with Holland even when we won in 08. Since Bowman left, everything has fallen to s***.
Holland's done plenty of good things. And some bad. Just like Bowman. Just like pretty much everyone who has dipped a toe in NHL waters.
Around these parts, I would argue he doesn't get enough credit. I tend to try and evaluate his work over larger periods of time that, IMO, have yet to expire.
