I giggle at this whole situation. Dave Meltzer needs to understand that MMA isn't Pro Wrestling. He came up through the wrestling dirt sheets, where you could just write whatever the fuck tickled your fancy. MMA being a legitimate sport is being hurt by having Meltzer associated with it in the first place.
Brock was a beast. It's comparable to Royce Gracie in the early UFC. Royce had BJJ, Brock had his size and natural athletic ability. When people started understanding what BJJ was all about, Royce wasn't as successful. With people understanding how to overcome Brock's size and raw strength it's the same situation. If Brock doesn't evolve his game he'll be an interesting footnote in UFC history.
But if Brock takes the time and effort to evolve, he's a scary proposition for any heavyweight.
