Everyone will have their own definition. To me it is a guy like anquan or even Russel wilson. You see russel wilson downfield blocking people for a TD next week?I still don't see what taking hits has to with being an alpha male. That term is used to describe someone's personality specifically in regard to them being a leader or a follower. If you tend to be a dominant personality and tend to be the leader instead of a follower than you are probably more of an alpha.
