I have no idea what they gave up, i think a draft pick, no idea which round. They were saying on nfl live that this probably means that Rivers is gonna be traded after the season.
They have made the decision that its gonna be Brees next year and therefore they can get some random guy who's capable enough to be an emergency qb to ride the pine behind Brees. I think if they were gonna go with Rivers he would be starting already. Brees is having a good year so far, enough to show them that he can do more of the same from last year. I think if they were trying to find a backup for Rivers, it would have been someone more capable. Feely has proven he is never gonna start and doesnt offer much assurance backing up a young guy in his first year of starting. the chargers are too good, to give up wins for the young qb.
