Several years ago, working LD league for a friend . . .
A player goes off the court to his mom who is IN THE STANDS. He had to blow his nose because of some boogies.
Anyway, I am T, and I don't see him off the court as he had snuck behind me. We have a quick transition and I turn to run down the court as the new lead. I take about 2 steps but never see the 3'6" tike underneath my legs. Down we go. All 220 lbs of me landed right on top of this little guys head. I did the best I could to not land all my weight on him, but I don't think I did a very good job. The ended up with a bad bump on his head, bloody nose, and tooth knocked out. I felt absolutely horrible.
His coach saw it coming, but was paralyzed to do anything about it. He felt bad too. Mom and Dad were very nice, and were quick to point out that they and their son were to blame, as I was just doing my job. Nice gesture by them, but it still didn't make me feel better . . .
