It turns out there is someone who can tone down the taunting and irreverent antics Marshall Henderson is becoming known for. His name is Marshall Henderson. Mississippi's flamboyant guard missed 12 of his first 13 shots and was 0 for 6 from 3-point range Friday when he finally connected for a long 3-pointer in a second-round NCAA game against Wisconsin. Then he remained unusually businesslike while scoring the rest of his 19 points and leading the Rebels to a 57-46 victory.
