Can/will the saints and the colts go undefeated?

over the years of american football we have seen so many freakin teams try to go undefeated but just can not do it simply because of pressure and the odds being against the team trying to achieve perfection. The 2007 patriots(18-1 is worthless), 2005 colts, 1985 bears and the1998 broncos have all tried to win it all being undefeated meaning 19-0, but none were succesful. Do you think that since this is the first time we have seen two 13-0 teams in the same season that one team is bound to go undefeated. if you are a 13-0 team you might as well try it because you may never know if you may get back to 13-0 again. 13-0 is pretty hard to do but 19-0 is damn near impossible. but at the same time history will and has to change sooner or later so why not now? So many people are acting as if 19-0 is impossible. "will" the saints and or the colts go undefeated?
