VanVleet gets a multi-year "partially guaranteed" contract with the Raptors and an invite to their training camp. Possibly a 15th man on the roster or possibly assigned to D-League.
No details on the terms. He won't be getting NBA dollars unless he sticks on the Raptors roster, but he's probably getting enough to keep him in the USA instead of Euro ball.
