John Henson has blocked 262 shots during his three seasons at North Carolina, only 39 behind Brendan Haywood, who blocked 304 shots during his four seasons with the Tar Heels.

"I take a lot of pride in blocking shots," Henson said. "It's what I do to help the team - blocking shots and rebounding. That's one thing that we got (is) scorers, but shot-blocking and defending is something that this team needs, and something I really try to do."

Henson, who averages 3.2 blocks per game, could set the school record by the end of the season. Roy Williams said Henson possesses two traits that make him a special shot-blocker: timing and discipline.

"You have to have great timing," Williams said. "You have to be willing to have great discipline to stay on the floor on the first pump fake, to stay on the floor in the second pump fake and wait until the shot does go up. Because so many shot-blockers can stay in foul trouble if they jump up in the air and foul the guy on the first pump fake.

"We do try to do coach it, but it's a skill and an ability that I think is natural to some kids and not natural to other kids," Williams said. "And to John, it is very natural and something he enjoys doing."
