Well, I remember in the bubble, Greener said in the words to the effect of, that he wasn't going to apologize for winning ugly. Despite being outshot and outplayed at times, he still pulled out some Ws and almost upset the much favoured Knights. I think he knew Vegas's track record, getting lots of shots, but not necessarily winning a fair share of those games. He knew he couldn't run and gun against the Knights, so his strategy had to be more defensive.
I think he was willing to give the Knights shots from the outside, but he had the players to clear out rebounds and most importantly, limit their high danger chances. If his team could keep the game close, Greener had some good talent who could score a timely goal to win it for them (ie: Petey, JT, BoHo, Brockstar, Toffoli, etc). Yes, Bubble Demko was superb, but I think we had some pretty good defensive guys that year who helped Demko see lots of shots or lay their bodies down to block a good chunk of them (ie: Tan-Man, Edler, Beags, Sutts, Fatenberg, Benn, etc). In my opinion, those guys did alot of the dirty/unnoticed work and helped Demko shine. Like I said b4, Greener's strategy wasn't pretty, but it almost worked.
U can criticize Greener all u want, but in the bubble, Greener was prob at his best. He guided his team to walk over the Wild, then knocked off the former Stanley Cup Champ Blues and almost upset the much favoured Knights.
