He speaks via his website:
The flipping off of the fans that just lined your pocket with millions of dollars is just LAME. He may be a Champion but he has a long ways to go before he earns the respect of a Champion. The fans are why we do this Brock, this sport is not about fat paychecks and drama it is about hard work and sacrifice for a shot to do what you did last night. It doesn't matter how much money you make if you can't earn your peers respect and the respect and love of the greatest sporting fans in the world. We have no scripts in this sport, no pre-determined earning amount and no pre-determined outcomes. It doesn't matter if you win or loose it matters how you win or loose.
He gives big praise to his upcoming opponent in Cain Velasquez:
From leaving the venue all the way to the Airport I have had fans of the sport ask me to take out Brock Lesnar for them. The thing is I have a very tough fight ahead of me that IMO is every bit as tough and talented as Brock. Cain is no joke and he may have had a tough fight against Kongo but I got rocked against Gonzaga. Fact is we are at the top of the HWT division and anyone we fight moving forward is going to be a real test. Cain is nothing short of a super athlete with amazing wrestling and he trains with one of the best camps in the country.
