we cant just go interchanging linemen as we see fit. have any of you guys ever played line, its totally different technique and mental prep for each spot, never mind the line calls the center must make, u cant just plug any slob in there and expect him to get it right, altough id rather have a moneky than mckinney. but seriously, some guys cant even switch left to right tackle cuz they cant handle the hand and footwork switch...
