I don't think it's too big a deal... Activity is so underrated, since all people want to see is fighters tested... I mean if all goes well, Williams and Collazo will at least get the exposure from being on the card and will probably both look great. Theres no reason they both can't fight soon afterwords, what's the harm in showcasing two of the best welterweights in the world on the undercard of an undisputed welterweight championship fight..
