Bam is the only player that can match Jokic on Heat. While Bam is inferior compared to Davis and Ayton.
Do you mean here by how Bam Adebayo putting the defense on Nikola Jokic? From a personal view, it's not even close to saying he's a match for Jokic.
Nikola Jokic is playing well even Adebayo is guarding him, and even against anyone on the Miami Heat. Did we even see Jokic struggling when Adebayo is defending him in Game 1 or by other Heat players? He was able to shoot 8 out of 12 field goal attempts in Game 1 and was sent to the free throw line grabbing 10 points out of 12 attempts. It's already showing that no defense is working against Jokic 1-on-1 and single-handled.
It needs two good defenders to make an attempt in slowing down Nikola Jokic, but that's not even sure if it will work. Even if the Heat were able successfully to slow him down, his scoring is the only one to be limited but he still can be a threat since he's a good playmaker and his average assists per game stats tell it all.
In several situations already when he's cornered, instead of forcing his way to the bucket, we will see him doing unexpected dishes to his teammates in a completely free zone shooting mode for an easy bucket. He is also good at low post especially against smaller than him therefore, 1-on-1 against Bam, he has the height advantage and can easily throw a floater in a post-up.
There is no one who can stop Jokic. If Heat will possibly be able to limit him in scoring, expect that he will instead have good stats in rebounds and assists.
