I think we need to calm down and trust Fisher/Snead.
First of all, Foles for swapping first round picks would be a fair trade. We could have cut Bradford, so why include him in the trade? Unless there are some cap ramifications I am unaware of, it would be because Philly wanted him. Chip Kelly is a strange dude, as he's shown - but no other team would realistically trade for Bradford with that contract. I believe Kelly wants Bradford, but that's neither here nor there.
IF we swapped first round picks, I have to believe we got a 2nd or 3rd or some other picks in THIS draft from Philly. Otherwise we could have just given up picks for Foles.
