Why did Lennox Lewis keep his hands down a lot when fighting?

He also utilized the "up" jab when his hands were low

Yup.

That was an underrated punch, too.

Because he was a tall, long fighter. Those very long arms (and a beautiful jab) are what allowed him to keep his hands low when he had his opponent at a distance where he could land but they couldn't. Sometimes it backfired.

Thanks. I understand now.

But why did he keep his hands down though? Was he conserving energy?
