Some of these guys have come out of nowhere to become useful players. Others, you knew last season, but clearly improved immensely over the summer.

Here are seven guys who have made a leap this season.

Lagerald Vick, Kansas

Vick was a useful 3-and-D player on a Final Four team last year. Those guys usually don’t blossom into stars; Kansas’ preseason hype pegged Vick as a solid starter, but not much more.

He’s making that projection look foolish. Vick is red-hot from 3-point range, shooting 62.5 percent from distance. He went 8-for-8 against Vermont and hit seven more against Louisiana.
