I want to see him face Garcia. Garcia will get knocked out though if he allows Matthysse to land as easily as Khan and Judah landed.
The Khan fight I feel is unnecessary for Khan to take with his chin. Maybe towards the end of his career as a nice paycheck. Khan can UD Matthysse but that is if I pretend that Khan's chin isn't suspect.
Alvarado will be stopped by TKO to the body.
Pacquiao will absolutely maul Matthysse, same with Mayweather.
Bradley will fight a slick fight against Matthysse. Either UD Bradley or RTD win for Matthysse as Bradley can't take anymore punishment after the 10th round (if Bradley fights fire with fire, which clearly didn't work against Provodnikov).
I will like to see Matthysse-Judah 2, Matthysse will stop Judah this time.
Matthysse is not as good at fighting on the inside as Bradley, inside-fighting is Alexander's nemesis. With Matthysse going hard for the KO, I think Alexander could be too slick on the outside, nevertheless, I am 100% sure that Matthysse won their fight 95-94 a few years ago.
Broner vs Matthysse is one any fan will want to see. I just cannot tell how that will go tbh in a few years.
