Harrison Barnes is a top NBA prospect. Most NBA draft outlets have him pegged as a top five pick.

With those kind of projections, you'd think the 6-foot-8 small forward would be a lock to come out. Not so, according to ESPN.com’s Chad Ford.

Barnes would like to win an NCAA championship for the Tar Heels before declaring for the draft, a source told Ford.

"He's the sort of guy who cares about more than just going to the NBA," the source said. "He wants to leave his mark."
