Undrafted Keifer Sykes was instant offense off the bench for the Cavs on Friday. Sykes scored 10 points on 5 of 6 shooting in just 16 minutes and had his teammates off the bench when he caught this nasty alley-oop over Adreian Payne of the TWolves.

If you liked that dunk then check out these 2 crazy alley-oops to the 5'11 high-flyer with a 44.5 inch vert.

Hopefully the 2 x Horizon League Player of the Year gets to stick around on LeBron's team, so we can see a lot more of these types of dunks which gets reactions like this, from stars like Chris Paul.
