I think everyone knows he can be hurt. That is why a lot view it as a 50/50 fight and some like me said it was a terrible first fight for Rios at 140.
That fight would have been stopped in the first round by a surprising amount of referees these days...
Alvarado was cut and busted up, but I never saw him stunned, staggered, or looking hurt like Rios was against Acosta. I could be wrong though.
I think this is going to be similar to Rios vs Antillon. Alvarado is going to run right in to Rios' punches.
