NCAA tournament preview: North Carolina vs. Arkansas Posted Mar 20, 2015 Can North Carolina put together a complete 40 minutes? The Tar Heels were the superior team against Harvard, pulling out to a 16-point lead in the second half. But then they seemed lackadaisical with their effort as Harvard started to chip away at the lead. Such lapses cannot continue into the tournament if UNC wants to make a run at a national championship. Arkansas poses its own challenges because of its press. (ESPN.com)
