In broad terms, there isn’t anything to highlight with UFC Vegas 48. The UFC has a huge roster and is contractually obligated to offer those fighters so many fights over the year. That’s the best way to describe the preliminary fights on the card, at least to the casual fan. However, to the fan who wants to know if there are unpolished gems that need a bit more time, there is something worth looking into. David Onama looks like he could be something special in a couple of years. There’s a large part of the MMA community that is high on Christian Rodriguez, but he is debuting on short notice at a weight class above what most believe is his best weight class.
