It also struck me as interesting - but more as a good reflection on Dawkins. He not only referred to Josh as the kid and younger brother, but also referred to other "young guys". To me even though he's only been in the league a few years, he really seems to consider himself a veteran and a leader (captain this year). That's pretty impressive to me.
Also you can just tell the love he has for Josh (like many of the other player's we've heard). When he said "I'd die for him" it almost gave me chills.
