ST. LOUIS, Mo. -

It is a rare occurrence for Kansas freshman Andrew Wiggins to step on the floor and not be the undisputed best player on the court.

This has become especially true with Kansas big man Joel Embiid sitting out with a back injury.

Wiggins has gotten more assertive as the season has progressed.

"He (Wiggins) is much more comfortable with what he's doing," Kansas coach Bill Self said. "He is much more confident and certainly when teams are designed to key on him he's been very poised in learning how to play out of that and not get frustrated. I think as much as anything, he's become more of a complete player."

Wiggins is averaging 28 points per game over his last four, but it is the other end of the floor where he sees even more room for improvement.

"(I need to improve on) just staying more engaged with everything and not always on the offensive end, more on defense," Wiggins said. "(I need to)try to get my man before he catches the ball, stay high on the floor, rebound more and just help my team in more ways."

Stanford coach Johnny Dawkins remains impressed with what Wiggins will bring to the court on Saturday.

"There is not one facet of the game that is limiting him from being successful. Can he shoot it from three? Yes. Can he bounce it? Yes. Can he finish around the basket? Yes. Can he board it? Yes," Dawkins said. "He is a young man who really doesn't have very many holes in his game and I think why he is so successful throughout his career."

Stanford and Kansas tip off at 11:15 am on Saturday in St. Louis.
