100% not a flagrant and not even sure how anyone could think that. Did he go at his head? Not even close. Did he undercut him in the air? No, Hart never touched Hardaway's body. Not even close to being a flagrant.
I replayed the video multiple times, and I'm still not sure if he even touched Hardaway's arm. Even if he did, it was after the ball was in the cylinder and out of Hardaway's hand. By definition, that is not a foul.
Legal play, defender ‘high fives’ shooter’s empty hand after release, no foul
I also reject the idea it changed momentum. This happened at the 3:09 mark in the third quarter, with Detroit ahead by 4 points, 80-76. I posted that at around the 9-minute mark of the fourth quarter, Detroit was up 98-90. So after the momentum changing no call, the Pistons increased their lead from 4 to 8? In 6 minutes of game time?
Even if it was 100% a foul, I don't want little BS things like that called. Outside of maybe Houston, my team plays the most physical brand of defense in the entire league. If you start calling little BS stuff like this, it's over for Detroit. We need to be physical, push/pull/grab, to play our style of defense. Calling crap like this would be a net negative for us. It will either lead to us playing softer defense, which is bad. Or our guys in constant foul trouble, which again is bad.
This play had zero impact on the game. It didn't lead to our shooters going ice-cold. It didn't lead to all the dumb turnovers. It didn't lead to us getting dog walked 21-0. It didn't lead to the layup line in our restricted area.
