Don't know that I'd feel good per se, but I sure as hell would be thinking that it's time to wrap this puppy up with all due haste as we know we can. That and how often are we going to lose a game (well, fail to extend it anyway) on a missed Dirk FT? Seldom and never, that's how often...
Mavs just lost focus at a bad time. They do that occasionally, it's their one real weakness, really, and it's probably why Avery stays on their asses no matter how good they get. He knows that they can go off track for any given stretch. And when they do, games like last night's happen.
But I do believe that this is not a team that's going to blow this series to a good but ultimately lesser team. The difference between this team and other Mavs team, besides depth of talent and better coaching, is their proven (so far) ability to fuck up and bounce back strong. And that's 100% mental.
Last night, they fucked up. Let's see if that bounce is still there. Betcha that it is.
