I'm saying that some of the skills for certain positions are mostly (not always) better suited for certain people, dunno if you agree or not. I believe this guy since he and his brother are pros and both OL. I think Samoans are the shit when it comes to big strong guys. You def got me there.
I absolutely agree that certain positions require certain mental and physical characteristics. For example, fullbacks are the smartest, strongest studs on any football team.
But I don't agree that any ethnic group has an advantage when it comes to the physical and mental requirements of any position. We had a guy at UH (Timmy Chang) who was Chinese. All-time NCAA passing leader. Has all the physical tools needed to play in the NFL, but I'm not sure he has what it takes between the ears (much as it pains me to say that). Is that because he's Chinese? No.
And why do you have to believe what someone tells you. Believe your own eyes man.
You're obviously a fan of the game too.
There are some insanely strong Samoans. One of the strongest players in the NFL, former UH and current Niners DT Isaac Sopoaga, is Samoan. I also know some very weak ones. One of my friends is married to a skinny Samoan lady. One of my friends is married to a "big boned" Samoan lady.
They come in all shapes and sizes.
