Your level of comfort with the Grigson thing basically comes down to how much you believe in the Peter Principle.
Clearly Ryan Grigson was talented enough at being a Director of Player Personnel with the Eagles to get hired by the Colts to be their general manager in the first place.
He unequivocally failed miserably in Indianapolis as their final decision maker. This is true. But does that failure mean he should not be considered for any future roles further down the trough, including potentially one he's already had success at?
It's a legitimate question.
