Suppose Rockets were to win game 7 and clinch the series over Mavericks, would you rather 1) win tonight in Dallas and lose in Houston or 2) lose tonight in Dallas and win in Houston? From a team psychological point of view, 2) may be better - it would show home is not all that bad for Rockets. But, on the other hand, losing 3 in a row might be a little too hard to swallow. What would you rather have?
I'd rather win the next two games. That said, I see the most likely scenario for us winning the series as losing tonight and then winning the next two games. I just think we're going to be too psychologically damaged during this game. I bet the team will play better with it's back against the wall in game 6. Then in game 7, it'll have everything to play for in a winner-take-all game that everybody will be up for.
