Both weigh-in below 168 lbs, Munguia and Ryder at 167.8 lbs, but it's good to see them making the weight.
https://www.youtube.com/watch?v=AJAY-koXMCwMunguia though looks fresh maybe because of his youth, but he is still the favorite in this fight. I wanted to see Munguia vs Berlanga though, I mean this two has been calling each other for quite sometime now and they are young that's why this fight is going to be equal though.
But let's see if Jaime can pass his big test against Ryder first.
It's their handler who brings fight for them they are just following the demands of promoters to make sure that there's audiences that will watch and bet for the fight, we don't know what are the plans but Munguia needs to win this and create a good hype to his name to call for a much bigger fight,
though like you mentioned this is a big test for him and Ryder will not waste also his opportunity to regain his name and climb back.
