No. It’s like a boxer fighting 9 rounds and then having a completely fresh second opponent of equal or greater talent replace the original opponent.
Hmm...
I boxed in my 20s.
It’s actually like training for a particular fighter’s style and then getting one with a different style at the last minute.
If you’ve been sparring like you’re facing a dance around the ring guy and at the last minute he’s replaced with a brawler..that’s a lot of trouble.
