I disagree that he is not in their league. This is about as close as you can get to 50/50 type fights. Castro was tough, a good counter puncher one of the best fighting off the ropes and packs a nice punch in his own right. Not sure I am prepared to make a call. I could see him winning both or losing both or splitting them. If forced to chose I would probably say I favor Valdez to beat him, but give Castro a decision over Briscoe.
Bump … 2 different opinions here to start these 3 deserve more than 2 comments … anyone else? maybe @Seamus
This is the essential truth...well said Bob,...Castro would have been manhandled by Briscoe and embalmed by Valdez.
