Can someone explain to me the difference between preseaon and garbage time?   the preseason is all about "we can't play our starters as they could get hurt"..or " we need to get guys experience and find what the backups can do in a real game situation"   and then in garbage time, like last night..I see Keenum, Von MIller etc all in the game with 2 minutes to go and the Broncos up 45-10? It amazed me in Green Bay when starters from both teams, including a banged-up Aaron Rodge
