Raptors Big Board: Top 10 prospects for Raps no matter where their pick lands

No. 6: Stephon Castle, Guard, UConn

Stephon Castle has made a late push up draft boards given his dominant close to the season and contributions en route to a second consecutive national championship for the University of Connecticut.

At 6'6" Castle has the size to play alongside another ball-handler, allowing him to play to his strengths. On offense he is strong finishing inside and a good enough ball-handler to get into the paint, where he is a good, not great, passer. His shooting is streaky and the biggest swing factor on whether he will be worth a Top-5 pick.

What is not streaky is his defense, as Castle is probably the best pound-for-pound defender in the draft class, at least among the top group of prospects. He can pick opponents up fullcourt, has excellent anticipation to stay in front of players, and his motor is always running. He is an excellent team defender, can switch onto larger players and essentially allows his team to execute a number of different schemes.

The Raptors can truly use a defender like Castle to pair with Immanuel Quickley in the backcourt. If Castle's shot can develop he would be an ideal long-term pairing; if it doesn't, the prospect of playing him and Scottie Barnes together (not to mention Jakob Poeltl at center) is a painful one for Toronto's offense.
