Russ Smith has played a great game against Oregon. He has an efficient 23 points midway through the second half to lead Louisville in scoring, and the Ducks have had no answer for him regardless of where he is on the floor.
The only player who can stop Smith? Well, Russ Smith. He tried to bring the house down with a monster dunk, and ended up doing this.
In all seriousness, Smith is lucky he didn't land on his arm or wrist. It appears he got undercut while taking off from the lane, and falling like that is a broken bone waiting to happen.
