Does he benefit from it.....sure. Does he benefit from a great head coach.....sure. Does he benefit from good management and ownership....sure. None of those are his fault and kudos to him for making the most of his opportunity. What you are seeing is mostly jealousy of the organizations success over the past 16 years and he just happens to be the face of the franchise and therefore gets most of the attention.
Seems like a solid dude and he will be a first ballot hall of fame QB. If he wins another SB or two he may end up being considered the greatest QB of all time.
