Swift vs Rios does good ratings and would prolly be entertaining.  Both dudes can sell a fight.  With that said, I'd prefer an opponent who has a lil more momentum going on in his career.  Collazo is a better fight imo since he's coming off that Sammy Vasquez win.  
If a nikka coming off a loss wants an easy fight, I won't hold it against them.  That's their right imo.  Now if the nikka wants to fight another top guy, instead, then hell be my guest, but I won't demand it of him.
The bigger problem is guys aren't fighting 3x-4x a year, so that one soft touch and one tough fight out the year just feels like nikkas careers aren't progressing fast enough.
