Positivity is a good thing just so long as they don't forget why they had a bad game and make an effort to not repeat it.
What I've seen over 8+ years here is the "scrap the bad games" mentality seems to also apply to bad playoff games and series. Which is perhaps why we see AM, Mitch & JT never evolve their game to adapt to tighter checking in the playoffs (Willie hasn't either but he gets a bit of a pass for at least showing up in games 6 & 7 last year).
Maybe the whole problem with this group all along is that they just brush the loses - all the loses - aside and take nothing away from them? To me, the circumstantial evidence seems to suggest so.
