Some ST coaches are so good that they outgrow their jobs. I hardly see this happening with Marciano.
Harbaugh spent nine of his 10 seasons in Philadelphia as the Eagles' special-teams coordinator. Andy Reid moved him to defensive backs coach in '07, largely to help him improve his chances of getting a pro or college head-coaching job.
"You get to that age and financial spot where you've got to make a move or you're going to outprice yourself as a special-teams coordinator," Reid, now the head coach of the Kansas City Chiefs, said Monday.
"John was climbing [salarywise] into the upper echelon of special-teams coaches. And you just didn't see DB coaches being DB coaches at that time for the amount of money John was making. He had to make the move or he was going to outprice himself or have to take a pay cut [to become a position coach]."
Harbaugh is one of six former Reid assistants to become NFL head coaches, and the first to win a Super Bowl.
