You obviously dont know much about achilles tendon injuries. Amare fell awkwardly and was damn lucky to avoid a serious injury.
If Bowen tries that play on Amare 10 times, Amare probably ends up injured 30-40% of the time.
The point is obviously not the severity of the tap. The point is there is absolutely no logical reason, excuse, or explanation for a clean basketball player with any semblance of a conscience or integrity to stick his leg out like that. Only bad things will happen.
Kicking a man in the back like that just shows what a low-life coward you are. Sort of like when Bowen instead of confronting Ray Allen like a man kicked him in the back. It's a trend with Bruce. He's the master of subtle, but inherently dirty (or pitiful) extracurricular activity on the court.
Sticking a foot under a jumpshooter's space is also very subtle. You could even call it a "slight tap" like you did. It's also very dangerous and dirty. And perhaps the 100000th time you do it, you lose the right to call it an accident.
