Check out this NASTY dunk by Daniel Skinner, a sophmore on the Jacksonville College Jaguars (which is in Texas, not Florida), against the Tyler Junior College Apaches on Wednesday in Tyler, Texas.
When the video is slowed down, you can see that the back of Skinner's left heel is just a shade in front of the foul line.
What goes unnoticed by most is that the referee actually calls a charge on Skinner on the play. A small consolation prize for the defender, who just had another man's crotch in his face while he got dunked. on. The people in the crowd however, don't seem to care about the call, and they proceed to go crazy after the jam.
Tyler Junior College won the game in overtime, 91-89.
