Leaders at their position
QB - Tony Romo, leader of the offense
RB - You can maybe say Joe Randle, but that's very questionable
WR - Dez Bryant
TE - Jason Witten
OL - Doug Free (when Free leaves/retires this will probably be Frederick)
This offense belongs to Romo and Witten, not Dez.
I would argue Free would be a captain before Bryant.
On defense
DL - Arguably it is Hardy, but it's hard to really make him a captain at this point.
LB - Obviously Sean Lee. Also the leader of the defense.
Secondary - Church. Probably was Scandrick before the injury.
I'd say in year two, Hardy probably becomes a captain over Scandrick/Church.
Special Teams - Easily Bailey
