In the NFL, if a team loses, the quarterback usually gets the blame. Except if the quarterback is a stud, then the coach gets the blame for not coming up with the right game plan. But if the coach comes up with the right plays and the QB executes them correctly, that's when the blame goes to the General Manager.
Because if it's not the superstar quarterback's fault and the genius coach is calling the right plays, they must not have enough talent around them to win. So this is where the GM gets to prove his worth, one time a year, at the NFL Draft.
If they did their job correctly the last few days, then they might get their share of the credit when the Vince Lombardi trophy is passed around.
And if they did a terrible job, that's when the blame goes to the owner...for hiring a bum of a GM.
