I think the whole thing about being named Captain, is that it has too feel natural. It one of those things that when it happens, everyone knows it's right. Like with Keith and Gary, and with Jetter...etc .
I love David, but I don't think putting a "C" on his chest feels natural, or right at this time. I think he has has a way's to go to get that - at least in my book. I can see that he's been taking more of an active hand on the field the last few years, but I still think it's doesn't feel right yet for me.
