You obviously didn't watch the same game. Two days ago you said all the Suns did was defend at time. That they didn't put a pull game effort into things. Now, to fit your arguement, you switch things up.
If you didn't read the stats, perhaps you should. It took an insane 180/windmill/reverse layup by Howard to give you a late lead and Dirk's jumper was well guarded. Where was this "championship defense" when the Suns scored on two layup/dunks to tie the game within the final 1:30?
In each team's final five offensive possessions, the Suns scored twice on a layup and a dunk and got to the FT another time, converting one of two. They had one turnover and that 1.3 miss by Amare. Dallas scored twice, the crazy layup by Howard and the jumper by Dirk. They committed two turnovers, one forced, and missed a baseline jumper.
Basically it came dowwn to Dallas having more time to get their last shot than did Phoenix. It's not like the Mavericks was stopping the Suns anymore than the Suns were stopping the Mavericks.
Again, Dallas shot 41% from the field, roughly five percentage points lower than normal and committed 18 turnovers, roughly four turnovers more than normal. Suns actually shot better than their seasonal average, but turned the ball over too many times, seven more than normal. That's a credit to Dallas' defense, but if one teams gets just due, then certainly the other should.
I just worry that none of these stats will reach your head, as it's stuffed too damn far up your ass for them to do you any good.
