This is without a doubt the next leap that Frank's game will have to make. As a PG, he gets rid of the ball way too soon far too often. In transition or when the D has been broken down and put into rotation, he doesn't force the help D to commit either to him or to his obvious passing target. He let's the D off the hook. He has to take another dribble or two into the paint to really make the defender commit to protecting the rim and then it'll open up so many assist opportunities for him.
He does this a ton in transition where he'll make his first pass to the wing while he's halfway between the timeline and the top of the arc and let the transition defender hovering around the FT line easily close out to the wing where Frank passed it. It's not a situation where the teammate on the wing is out in front and Frank is advancing the ball either. That extra dribble or two, make that defender commit to stopping him and then the wing or corner three will be wide open.
I wish I had the time to put together a tape of all the times he does this. The good thing is it's just a "learning the game" adjustment/development. He has all the tools, he just has to realize exactly what's happening in those situations and punish the defense for it.
