"Playmaking" is an over used term and often misused in my opinion. It seemed to me that the idea of the comment was more assists and facilitation of others. That is one type of play to be made but not the only type. Driving to the hoop and getting fouled is a play to be made too.
I feel that Brown and Tatum make plenty of plays with the exception that both could draw more fouls and in particular Tatum, needs to anticipate and deal better with double teams. Dealing with double teams is about the guy with the ball but also the spacing and movement of the rest of the team.
I don't think there needs to be a focus on getting more Brown and Tatum assists per say. When you pass out of a double team, the good look for someone may be after 2 or 3 passes so this isn't just about Tatum's and Brown's assist numbers.
How ever you want to frame it...if possible a bit more Bird, Magic and Lebron will never hurt. Multiple players getting open looks, no matter if it's after 2 or 3 passes stresses out defenses, and gets pace moving at both ends of the court.
I agree, Bird, Magic, LeBron all could/can kill you when you double team them. It was a big part of what made them great players and made their teams great. No doubt that Tatum in particular needs that in his game if he is going to get to the next level. Magic had the additional ingredient that he could take the ball as a PG and make things happen in transition or fast break. Tatum is probably not going to become that and I don't think he needs to. For now, just make them pay when they double team. Single team, I am happy to see him take a good shot or take it to the hoop to draw a foul, especially if there has been a switch and you have a favorable match up. No need to look to pass more in that situation.
The key with double teams is to see the double coming and start the counter play before the double gets to you. Tatum had a tendency to wait too long. He is probably still learning how to recognize it is coming. There is also the element that the rest of the team needs to react accordingly. As soon as your man leaves you, you need to cut or otherwise move to find a good spot to be a target. But you should be moving to make defensive adjustments harder, not just standing in the corner or where ever. This team off ball movement was not great last season in my opinion. The result should often be a fairly simple pass. It doesn't need to some play to be made that gets on ESPN. Kind of like a football team that takes what the defense gives you.
I expect to see improvements in all these things, better recognition from Tatum/Brown, better team off ball movement, better overall team passing/execution. Much of this may need to start with Tatum/Brown but that is only the first step. Good coaches are going to throw the kitchen sink at Tatum and to some degree Brown. The whole team needs to be ready for that, not just Tatum. If our coaching focus is only on Tatum and Brown, that will not be enough. Instead of Tatum looking for a hero shot, he will be looking for a hero pass. Neither is going to get him or the team to the next level. That is why I have this kind of pet peeve about the emphasis on "playmaking". I just feel it often gets misconstrued.
