I think this is going to be something we as fans are going to have to live with for a while. Right now, at 22 and 24 years old, it's important for the Jays to learn to create their own offense. While they get very comfortable knowing they can efficiently create for themselves, both players will also learn to use those moves to create for others.
For instance, both Brown and Tatum have been finding new ways to get to the basket and attempt to finish. Sometimes, they put up terrible shots in traffic in the lane surrounded by collapsing defenders. They WILL eventually learn to kick it out to the open man in these circumstances. Then they will learn to see it coming early enough to get that pass off earlier for more wide open shots and less turnovers. And they will learn to be much better in pick and roll offense as they do it more and more.
It's going to happen. But learning playmaking takes time. It took Kawhi Leonard until he was 27, almost 9 years in the league, to average 5 assists a game and learn to create for others. DeMar DeRozan is another guy that took a while to learn to create for others. Even Kevin Durant took 5-6 years before he started to become the playmaker he is today.
We will need patience as fans. Right now, both guys are still learning how to be the focal point of the offense when it comes to scoring. They will get better at involving others as they have their hands on the ball more and more.
Patience.
