O.k patriot fans this is for you or any one eles ?

if tom brady somehow reinjures his ankle and the patriots loose because of it , will they still be the greatest team ever in your eyes ? the reason i ask is because i always wonder if ben roethlisberger would of played all 16 games in 2004 would the steelers have gone undefeated ? would being undefeated helped the steelers in the playoffs ? if jim mcmahon would of played all 16 games in 1985 would the bears have gone undefeated ? if jerry rice and john taylor would been on that 84 49er team would they have gone undefeated ? better yet if tom brady would of missed any games even one this year would the patriots still be undefeated ?
