I disagree. Say you have a guy whos real good at half back so you dont want to waist him on D. When you get a real good program and have great players you want to keep them fresh at what they do best. Also, coaches dont really like playing QBs both way wether your teams good or not. Zions QB, daniel Pugh, has no line in front of him and is real injury prone so we try to keep him of defence. But i see what your sayin i play WR, CB, and special teams, if im not hurt im playing.
