I agree with what you're saying about it possibly weakening the Lightweight division. But in a year or so, they will be able to adjust better. Fighters like Guillard, Stevenson, Sherk, Fisher, Stout, Florian, Alves (if he moves down), Diaz (if he moves down) will all be more comfortable at 155. And that's a pretty decent list of fighters for a division, not counting all the up and comers over the course of this next year. And fighters like Lauzon, Edwards, Hominick, Griffin, Dent, Curran (if he ever signs with UFC), possibly even Pulver might be more comfortable at 145. And that too is a pretty nice lookin list of fighters. Give it a year or so I say and it will be feezable.
