Did it for different reasons. Chargers were afraid of Brees shoulder. Colts had to consider that Manning had to get multiple neck surgeries, would have to pay number one pick luck and Manning at the same time, and the Colt's were a one win team the year prior. (Also luck eliminated peyton from the playoffs head to head). Brady and the pats are close but the pats just didn't wanna pay him and extend their cap penalties. Remember the pats were cap strapped. None of these had to do with the players skill set though. Goff did.
