Awesome bit of matchmaking.
Oddly, I thought Quigg was over-rated & protected as fuck at super-bantam (massive weight-drainer with a huge advantage over everyone, meaningless belt won vacantly, kept him ticking over in 80-20 fights until they could get the money for the Frampton match, all things I pretty much despise) but Valdez, after all that title-winning hype, was well-exposed by Marriaga IMO. Didn't see his fight with the Filipino fella, I have to admit but I thought the Colombian exposed his limitations.
It's gonna be a tight fight, IMO. Now Quigg is with Roach he's twice as easy to hit as when he was with Joe Gallagher, but at least he throws punches now (see: the Salinas & Frampton fights, or, at least, half of them), & he's so big & awkward that Valdez is gonna need that Hail-Mary counter-hook that turned the Marriaga fight around late when it looked like Valdez was hurt & tiring.
