I'm not reading too far into that…GSP has been training with Renzo Gracie since before he could speak english, so I don't see that being a problem for him..if anything, it could have been a boon for him when he took Serra down.  As far as Matt Serra giving Dan Hardy the "secret" to beat GSP?  What exactly would he tell him?  The fight may start on the feet, but I can see GSP using a similar strategy to the one he used against BJ Penn…tie him up to get his arms and shoulders fatigued, so the punches come slower and once that's accomplished, play the range game to get the takedown.  It's going to be interesting to see how range factors into this fight…Hardy likes to back up and get you to follow him into range for those hooks and GSP entices guys to come into him to get the takedown.  Also, at longer range, GSP will throw a lot of kicks, since he's apparently not too worried about being able to shut down any takedown attempts.
