I beg to differ, one of them Charlo boys is heading that way. They have the skills, just need a couple more good fights. Both won't stay at 154, it's too crowded. They are the future and the only trouble I see for them at 160 is Trip G. Let the games begin.
Quillin is poor. There are enough guys actually in his weightclass - 160- who beat him easily. He should worry about them. Who cares about 154 guys beating him?
Canelo Lara Trout Cotto Charlos I'd say all of them trouble Quillin regardless of size. Not saying I'd pick all of them to beat him, but I'd expect for some of them to defeat or win 4-5 rounds, which would seem to be more than the TS is saying is acceptable to believe would happen, off of Quillin.
If any move up.. it will be because Canelo does, because he just plain cannot make 154 anymore. Then others will move up to fight Canelo. It will just be a farce though the "GBP league", where 160 is a worldwide division.
