As of now I think the question would be is how would today's Welter's stand up in Tito's era. I think the only one that would hold his own would be Mayweather, the rest get destroyed by the top 4 or 5. To answer your question though, Tito ruins all of these guys with the exception of Mayweather and I would consider that a toss up and couldn't pick a winner. Tito was a monster @ 147
