I still find it a win/win.
Washington was a sub par team for more than a decade. They'd gone through a litany of bad QBs. They needed a franchise QB in the worst way.
St. Louis was still in the 'we hope our #1 overall works out' phase. 2 seasons is too early to judge him.
Washington got what it hoped for when they made the trade. Becoming a team that matters within their division. St. Louis has added a lot of talent. And are in a position now, where if they determine that Bradford won't ever be that guy -- they can move to a succession plan with the picks they have.
The Redskins problem isn't the trade. It's the fact that they generally don't draft well outside of the first round. Alfred Morris notwithstanding -- they don't have a good player evaluation group there. They've been pretty fortunate on their day 1 picks, although they've mostly been in the first half of the rounds. Losing the 2 first round picks hurt them some, but I wouldn't say whomever they could have taken would have had better returns for them. Especially if they were reduced to starting Rex Grossman for another year.
St. Louis has started to draft well. That team is talented and is building rapidly. If Bradford is holding them back, they are in a position not unlike we were last year. A ready built team to compete but missing the QB element.
