This. It depends on the weight. Probably a catch, somewhere between light heavy and cruiser. A fat Toney has no chance against a prime heavyweight Walcott. A super middleweight Toney was fast and has the berst chance. He still gets a boxing lesson over 12 rounds but would make it interesting on the inside. I could see Toney landing some wicked counters on the inside to the body and landing some lead shots. Don't know if he's got the power to drop or stop Walcott. His hands are quick enough to keep him in the fight though.
I've seen Maxim fight, he's solid but not as good as Toney. Maybe the Maxim loss was a robbery though, Maxim got a gift against Patterson
Maxim was the Jimmy Young of his day. Little power, didn't look all that good on film, but somehow was the ultimate spoiler. His win over Patterson was not as bad as it is sometimes made out to be.
