The Tar Heels came out strong in the second half, building upon their lead and burying No. 16 seed Vermont 77-58.
James Michael McAdoo had a season-high performance for UNC with 17 points and 4 steals, and Zeller got a double-double with his 17 points and 15 rebounds.
The Catamounts were outscored by double-digits in both halves and the Tar Heels simply proved too much for them to handle.
UNC will advance to play Creighton on Sunday, where Harrison Barnes will take on his former high school teammate and fellow All-American, Doug McDermott, for a chance to play in the Sweet 16.
From the ESPN Recap:
The Tar Heels didn’t turn in a rousing performance, but they had a danger-free afternoon and advanced to face Creighton on Sunday in the third round of the Midwest Regional. They also bought Henson another two days to recover from that sprained left wrist.
