I think Sal lands with enough clean counters to carry a decision over Saddler. A slick, boxer type like Pep would be more a nightmare for Sal. I would take Pep to outbox Sanchez.
I think a taller fighter who's slick, long and doesn't mind letting the other guy engage is awful for Sanchez, moreso than someone the same height. Someone like say, Laguna. I'd take Laguna of the Saldivar fight to beat Sanchez in similar circumstances. Another guy I think would be a really, really hard fight for Sanchez is Legra. Here, I'd take Sanchez to paint Saddler at mid range - which would be the difference on the cards - but get caught up by that suffocating inside game and have to take some brutal punches. The problem I have with picking Saddler, is that it's obviously a fight where he'll be smothering most of what they do, and I can't see him landing cleaner than Sanchez in the exchanges where Saddler can't wrap him in a clinch. I like Sanchez on points.
Funny, I think it might actually be the other way around - I could see Sanchez potentially having too much all-around talent for Pep, but Saddler potentially smothering Sanchez's talent with his ugly spoiling tactics.
