Too big? GSP usually walks at around 190-195. He makes huge cuts to get to 170 which is why he is absolutely ginormous for welterweight.
Tonight you saw about a 15-20lbs weight disadvantage. You saw Penn at his natural walking weight coming into this fight and you saw GSP probably at around 185 once he got the water and food back into his body.
GSP is absolutely massive for 170 and would be the same at 185.
Silva has superior striking to everyone. That much he has put on display with everyone. He also has an underrated ground game, which he put on display against Hendo.
But what he also showed versus Hendo is how easy it is to gain top position versus him.
The thing you saw tonight is pure domination in how to control a BJJ artist. GSP sat inside Penn's guard for quite a while and was never in trouble. BJ has one of the most active and lethal guards in all of MMA and a submission never came close. That is simply incredible.
Now GSP is going to put Anderson on his back for an entire fight and control him from the top? Anderson has a good guard and very underrated I must say, but he doesn't have as active a guard as Penn, nor does he have the credentials as Penn off his back.
As I said, Anderson has no prayer to stop GSP's relentless takedowns. Heck, who does? But GSP's top game would control Anderson throughout an entire fight.
That is granted GSP doesn't get stupid and think he can out strike Anderson.
