VIDEO: Duke's Grayson Allen trips Louisville player

Grayson Allen just became one of the NCAA's most wanted after the subtle cheap shot he delivered Monday.

In the contest between Duke and Louisville, Allen went for the layup, he missed it and hit the ground, pleading his case for a foul.

As Cardinals forward Ray Spalding gathered the rebound and made his way up court, Allen extended his leg out and tripped him, earning a flagrant foul in the process.
