Let's face it, we gifted that game to the Bolts. A turnover by Miro, a missed hip check by Esa, and we are down 2 goals early. Probably not too many wins come with 2.5 free goals. Yes, the 0.5, IMHO, is Rads getting that late period reputation mostly penalty, gifting the Bolts a PP on clean ice.
Add in at least 2.5 missed shots on great scoring chances, and voila, you get a 5-2 game.
I also think Cooper has figured out Bone's breakout system and countered with a strong forecheck to stop our rushes, cause turnovers, etc. Bowness did a good job of tweaking with several weeks to think about it, but the "book" on him is he is slow to correct things in games and maybe in series.
I think they put up a good fight in game 4, but somehow screw it up, then get demoralized, the cave in game 5 on the back to back. Just MHO.
