Post scans of someone stating that chidori and rasengan cancel each other out, every, single, time. The few times these justu's clashed was when they were giving it their all. Rasengan and Chidori aren't opposites in affinities so there's no reason to believe they cancel each other out. Naruto and Sasuke are good at matching each other chakra.It's canon that they would cancel out, nothing anyone says would change that.
That's the thing, you don't know what Kakashi considered the worst case scenario.
Either way, it doesn't matter since they would have just killed Sakura in the process instead of clashing meaning none of them would have won.
Kakashi considered the worst case scenario is Sasuke dying, not them killing each other, which would be more reasonable as they are both his precious students. That obviously means Sasuke's odds of surviving that exchange would of been less likely than Naruto's
Sakura wasn't that close, she'd be caught in the explosion but she wasn't as close and Kakashi was. Kakashi was at "sandwhich" distance, Sakura was getting there though.
