QB’s and wide receivers operate on self belief in their roles as passers and pass catchers. Brady is the most competitive and does his best under pressure and is very demanding of his receivers to run their routes properly. I don’t know the man personally but from what I’ve seen on the sidelines he definitely carries a huge ego with him. Wouldn’t want to cross him;)
All of the great ones have that need to win and play at a high level. Joe Theisman, former Redskin qb, and Jim Harbaugh, former Bear’s qb and current Niners’ coach both seem to be in love with themselves and very self absorbed at times.
The great wideout from Detroit, Calvin Johnson, seems unshakeable in his desire to compete at a high level but never appears flashy on the field but we all remember Randy Moss and Terrelle Owen, not for their exploits but for their prima donna personas.
All your great linebackers were ferocious tacklers (Butkus, Taylor, Ehrlacker, Seau, Huff, etc.) on the field but only Taylor acted out off the field and snorted coke at halftime. I think all the fame and money was too much for him to handle.
The former defensive back, Deon Sanders (primetime) is still in a class by himself, ego-wise.
