I don't have a problem with Demar taking the final shot, but it's gotta be a better shot and setup than that. Everyone is the NBA knows he does the fake to his ball hand side then the turn around fade away garbage.
Even Leo "everything Derozan does is right" Rautins pointed out the easy lane drive he passed up on the final possession when he first caught the ball and his defender out of position to stop it. But instead he waited, let him get set, and did the Derozan special, inevitably resulting in a miss.
