Just like the difference between a major league baseball player and a AAA player is consistency, the difference between a college-basketball powerhouse and a low-major is doing it for a full 40 minutes.
And talent...and a bunch of other things, but you get the idea.
Today, the Vermont Catamounts stuck around with the North Carolina Tar Heels, but a baby-blue surge midway through the second half put this one out of reach, as the Heels advanced with a 77-58 victory.
Down only 10 with 14 minutes remaining, the Catamounts could not slow down one of those patented Heels runs that we've seen so frequently from this program, which included a 23-10 run over a seven-minute span.
ACC Player of the Year Tyler Zeller, and James Michael McAdoo, who has really come on strong and provided a tremendous boost to the Heels frontcourt in the last month of the season, led all scorers with 17 points.
John Henson sat today's game out with a wrist injury that was suffered in the ACC Tournament. His status for the Tar Heels' next game, on Sunday against Creighton, is unknown, but reports say head coach Roy Williams is just being precautious until Henson's presence becomes much more important.
