Manning and Brady have since went on to earn their most after their big paydays.
Manning has not won another SB. In fact, his team sold him out because of his contract for someone new.
And while he sure as hell "earned" it, this he was overpaid tripe only comes from the mouths of retards...like you.
im assuming you mean "underpaid" not overpaid. the fact is, he over performed what he was being paid. it happens. watch Grahams next contract. the guy held the record for TEs (maybe only for 10 minutes). he will get a big contract. will you again be complaining about another player getting paid for his performance? you get shite done, you get paid. your pay is based on what you have done, in hopes of what will happen. not vice versa.
he could play well no matter who the coach is. Manning is a great example of a great QB.
if your standard of a great QB is being able to play under ANY coach, idk what to tell you. why do we even have head coaches then? a head coach is exactly what the name implies, THE HEAD. without it, the body dies (to quote 3G).
