Giant Killers: Which underdogs could become tournament stars?

Twelve months ago, Sindarius Thornwell was in the midst of a very strong senior season at South Carolina. He was known by college basketball fans, sure, but it wasn't until the Gamecocks' Giant Killer run to the Final Four that Thornwell became a household name.

Just as everyone loves an underdog team in March, everyone also loves an underdog team's star. While players like Villanova's Jalen Brunson and West Virginia's Jevon Carter will get plenty of praise come tournament time, today we're interested in the face of the next underdog darling. And no, for the sake of this exercise, potential top-10 picks like Trae Young don't qualify, even if his team is rapidly descending into Giant Killer territory.

Keep an eye on these names, because one or two of them will be busting brackets in the near future.
