Dont be silly. Pacmana been endorsed for years by Nike amd will continue to be. Try checking the Asian Nike site. All Pacmans apparel is from Nike.
When did I say he doesn't endorse Nike? I said they scaled back on his products and promotion. Which they have. Just go back a few years ago - this dude used to have sneaker and apparel releases for EVERY fight. Now you'd be pressed to find anything new.
And this happened around the time he had the controversial comments about homosexuality around the same time Nike came out in support of gay marriage. Nike hasn't had a Pacquiao update on its news site in 2 years: http://news.nike.com/search?utf8=✓&search_terms=Pacquiao
All I'm saying is that it's possible that he just wore the shirt. He's a Nike athlete. He and Kobe are good friends. And Kobe's shirt is the one you can actually go to Foot Locker and buy right now. I also don't think it's impossible that they were having some fun with the nickname too :hulkshrug:
