I don't get the reference.
Maybe I can help, here is something everyone can probably relate to.
John Cooper's last team was 5-0, before the wheels came off. Lost at home to lowly Minnesota, lost at Purdue (ok, Drew Brees Rose Bowl team), lost at home to TTUN, lost bowl game to South Carolina. This is what I think of when someone says "...but, 5 and 0!"
No I don't think things are going to get that bad, but I just don't think it's likely this team is likely to go undefeated unless they play better.
