Cleverly went into the fight thinking he could outbox Kovalev but found out Kovalev is a better boxer than he is. He felt Kovalev's power in the first minute and was just trying to survive after that. It wasn't that he didn't want to throw punches, he did, he was just terrified of leaving himself open for what was coming back the other way.

I liked Kovalev's reaction to getting his anthem booed after he won.
