The Bulls never had to deal with the prospect of a dude hitting 30 foot threes with a PF that could also stretch the floor accompanied by two guys on the wings that hit nearly 40% of them as well. That was a completely foreign concept and just assuming they'd be able to deal with it is crazy. Rodman did not have guard like lateral quickness when he played for the Bulls, he was in his mid 30s bruh, he was quicker than the average PF at the time but he wasn't approaching guards. Also, we saw Anthony Davis, someone with incredible athleticism, length and mobility get absolutely destroyed when he had to guard Curry on switches, Rodman wouldn't do any better if he got caught on an island with him.
Nevermind the fact the Bulls didn't hit enough threes
