The New England Patriots!
Because the previous managers didn't pick the strongest teams of players available
Sir Alf Ramsey was the manager of the England Football Team in 1966 when they won the World Cup.
I would say the Houston Texans.
One of their managers' surname was "Symon".
No, managers are usually paid for their services.
