That play just now, McCallum spent a good 5-10 seconds trying to pass the ball into that guy who was trying to post up way to far away. The guy he was trying to pass to couldn't get open or create any space or give him a good target to pass it into. JT, Cousins, Landry and even Hayes would have been able to use their body to position it to receive that pass.
McCallum didn't force it into the player and cause a turnover, he backed it out and looked for something else which is something that tells me he does have the understanding to run the point.
