Meh. I play basketball weekly, watch it almost daily, and have followed it for years. The only one that was really obvious was the 5th one. And a lot of that is more of a function of physics from what happens when somebody who is a 140 pounds runs into a guy who is pushing 250. Bad stuff happens when there is a weight disparity. And the lighter guy usually loses.
The rest of them were just fouls. Most of them of them stupid, but they are still fouls. The fouling team will go into penalty and the other team will be able to capitalize on it.
I'm 6' tall. If I'm guarding a guy who is 5'5" and he is driving to the lane, simply sticking my arm straight out I'm at his head level. I'm not intending to do it, but there are just things that happen with height and weight disparities.
I'm not that heavy of a guy, at only 170 pounds and 6' tall I'm pretty lankly. There are guys I play against who are in the 250+ pound range. I *KNOW* I'm going to get beat the fuck up if I try drive the lane against them. It's not intentional, it's just what happens with that kind of size difference.
