Other than Billups seeming to have a "reluctance" in his game, (possibly leftover from his injury), Detroit didn't look "rusty" or "off" or "not hungry" to me ... they looked like Detroit ... the same Detroit that we've seen all year, nothing less, nothing more. This is not as great a team as many seem to think they are, and they're playing like they have for most of the season.
Even their shooting percentage was just slightly lower than their average for the year, and the rest of their game was played pretty well for them overall. I don't know why there is such a reluctance to give credit where credit is due, but the Celtics played better than Detroit, plain and simple. Detroit wasn't tired or rusty at all ... sorry, but I didn't see that one bit. I saw a team trying to catch up to the run-game, a half-court team that's too slow to do so, and has been for some time.
The Pistons can't defend an up-tempo offense, and that's what was used last night for the most part. Chauncy can also NOT defend Rondo effectively when Rage is attacking ... he's way too slow even at his best. The Celtics ran and attacked last night, and if they keep doing that with consistency, the Pistons don't stand a chance. I doubt they WILL keep running for the whole series, however, as they seem to get lulled into the half-court by a bit of laziness and their opponents' propensity to pull them into it.
The games that we lost this year to the Pistons, were games which we played about as poorly as we could play, and yet we still made them very close games. The games we won against Detroit this year, were games when we played well, and we blew them out. I don't know why there's so much surprise about this, but when both of these teams are at their best, the Celtics are just a far better team ... period. Does that mean we'll have an easy time in this series? I seriously doubt it.
The Celtics have also shown this year that they are their own worst enemy, and they seem to be continuing that in the post-season. I'm sure they'll have a "let-down" at some point, as they have in the last two series, and the Pistons are one of the best at taking advantage of such waning performances. However, the Celtics also seem to play much better against "better" teams, and from what happened in the regular season, I think people are giving Detroit far too much credit, and I don't see this series as being anywhere near as close as the last two.
