Trust me, this doesn't mean we'll sweep the Knicks, or even that we'll win in 5, but trust me when I say that the Knicks needed that victory last night, and the fact that they didn't get it, will prove significant.
Those wins have a mental aspect that can't really be placed in stats. They can give one team more confidence, and they can really deflate or be very costly for another team.
I feel that such a loss for the Celtics came in game 3 last year of the finals against the Lakers. There is no reason the Celtics should not have won that game. Everything for the Celtics was clicking when it mattered the most. KG even looked like KG of old, but Ray had a really bad night that game, after coming off one of his greatest shooting performances ever in game 2. I think us not taking that win ultimately robbed us of an opportunity.
Even Pierce, who was off for most of game 3, started to deliver when it counted most late in game 3, same for Davis. We should've had game 3 of the Finals, and we should be defending NBA champions as I'm typing this now. But the Celtics were so good that they actually managed to give themselves another great opportunity to win the Championship in game 7, but then we couldn't hold our lead, and gave up way too many rebounds.
