You said it perfectly, his speed was his advantage at 155, and will no longer be a strength at 145. Aldo is faster than Edgar and has better technique and heaps more power. What I do think is that Dana White is smart doing this as he won't have to give Edgar a rematch with Ben Henderson, a fight NO ONE wants to see. Frankie Edgar is a bore really, that could be why Dana doesn't want him getting a second chance at Ben Henderson. If he wins, that LW title is back around Frankie's waist, and any ME with him in it loses the company money. I say Edgar takes it, gets his ass whupped, and retires.

But that's just me being a dick.
