The Tar Heels get hyped on a yearly basis but haven't appeared in the national semifinals since 1993. Strength: Attack. This unit is a matchup headache with Marcus Holman (Gilman), Jimmy Bitter (above) and Joey Sankey. Holman leads the country with seven assists. Weakness: Defense and goaltending. The Tar Heels have been porous at critical moments, allowing double-digit goals seven times in 2012. X-factor: Chad Tutton. Freshman midfielders rarely score 20 goals in the Atlantic Coast Conference. He did last year, and if he takes the next step, Carolina's offense will be close to unstoppable.
