Paul Williams Welterweight Return May Happen on May 8 - Boxing News

An excerpt from the article and a quote by Dan Goosen,

If we make the decision to go back down to welterweight, the statement we want to make to all of the welterweights is ‘don’t dare say you’re the best welterweight when Paul is in that division. Don’t dare say you’re fighting the best welterweight unless Paul Williams is in the other corner.’"
Also Goosen says he talked to Williams trainer that a drop to 147 wouldn't be a problem.

The man was run out of the welterweight division because everyone ducked him. If Tommy Hearns another 1 of my favorites was around today, the same thing would also happened to him. In a way I don't really see any of the top welterweights taking him on. It's considered to be too risky and the reward isn't high enough.
