After next week, all (or most) of the top guys at 154 will have recently fought.
This week alone Austin Trout, Erislandy Lara, Ishe Smith, Charlo twins have fights. Next week Julian Williams. Last week Hugo Centeno. A month or so back Carloss Molina, Vanes Martirosyon, Willie Nelson.
Match-ups I'd like to see next. Jermell Charlo vs Austin Trout and Jermall Charoo vs Vanes Martirosyn and Julian Williams vs Ishe Smith and Hugo Centeno vs Willie Nelson.
I like Vanes. Look forward to seeing him in action... I'll match bets on JRock vs the division. I like the way he's progressing, & think he's ready for Anyone at 154. We will see
Is Trout ready for another title shot or does he need to beat a Charlo?
He needs to string together some wins over some better quality opposition before getting anywhere near a title shot. A tournament like you suggested would help clear up who's actually worthy of a shot at 54, right now no one sticks out.
