Wow, off the boards for a couple of weeks, and one misses a lot.
BJ has been walking around at 165-168, which makes him small for 170. GSP cuts from 190, and after hydrating rolls into the cage at 183-185. Too much of a size advantage for GSP. I would rather see GSP move up to 185, BJ move up to 170, and Anderson move up to 205. In all three cases, there is nothing left for them at their respective weight classes.
Maynard would get owned by BJ. They have trained together previously, and BJ used to MAUL him. BJ's striking is too crisp, and Maynard would not get the takedown. I heard BJ is scheduled to fight Frankie Edgar in April.
