If Forrest were to be fighting today how well would he do against the top WW / Jr MW such as Floyd, Thurman, Spence, Lara, Andrade, Charllo, etc. I think the Viper would have been trouble for any current fighters. The only guy who I think would have a slight chance would have been either Spence or even Porter.
Better matchups at welter where he was at his best pre shoulder injury. Spence may have the tools to beat him but still a bit early to say. Porter gonna give him hell stylistically thats for sure. He would defeat Thurman, Garcia and Brook by varying degrees of ease. Horn defeats him.
No way Horn beats Vernon, that's an insult. I agree with everything else WhataRock wrote. Styles make fights and Spence/Porter/Horn style makes it difficult for Viper but Spence and Porter are on a different level than Horn, imo.
