While he wasn’t selectedin the NBA Draft, Branden Carlson did sign a two-way contract with the Raptors! Source
Signing a two-way with an NBA team as opposed to getting a summer league roster spot is preferable. This type of contract will allow him to make more money than a standard GLeague player, it makes it much more likely that Carlson sticks with the Raptors, and he will likely get ample opportunities with their GLeague team.
Very happy for Branden!
