re: I WANT TO CHALLENGE ALL THE SELF APPOINTED EXPERTS

First off, in modern day pro football there is very little difference between the two positions. So, theoretically, there shouldn't be any difference, except for a scheme here or there. You obviously know the traditional differences, but I would say a willingness to stick your head in a pile is the big difference. That's one of the knocks on Smith. Doesn't want to get physical, doesn't want to hit. I don't care how big you are, if you're not willing to hurt yourself, to violently throw yourself at another person at full speed, then you can't play def in the league. Scouts aren't sold that Smith, a former WR, has that mentality.
