The interesting thing about all of those trades other than Atlanta moving up to the 1.6 is none of them worked out positively for the team trading up.
Personally, I think it is a bit early to judge 2013.
Even with RGIII, I guess we could qualify it with "so far", but even there it has been mixed. 2013 a struggle, but perhaps that should have been expected to some degree coming off the ACL injury (agree NOBODY saw the scale and magnitude of the collapse coming), but he was brilliant in 2012 - there is a concern that he will have a different projection and will be easier to defend if you subtract out his willingness to run, when that was a huge component of what made him special, his Olympic-caliber hurdler wheels. But, what if he is a 10 time Pro Bowler and Hall of Famer? IMO, far too early to call these trades yet. Dion Jordan could be a star (I thought he was going to be based on my limited scouting of him, don't know why they couldn't get him on the field. He was hurt with the shoulder to start the season, Wake is one of the best, and I'm not sure they knew how good Vernon was? Blackmon has shown he can at least be very good and possibly great, but he needs to get his life straight.
In another thread (should HOU move up, possibly?), someone pointed out that neither team won the RGIII trade because both teams finished last in their respective divisions. Does that mean WAS "won" in 2012 because they made the playoffs? Look at the Bengals threads, do they think their team is "winning" when Dalton makes the playoffs but does a faceplant in the first game his three years in a row, or with Marvin Lewis being the first HC in NFL history to start his playoff career 0-5? The STL QB missed more than half the season, so if that impacts the W-L record, does that mean they "lost" on the trade? Again, it is early, what if STL gets 7-8 eventual starters and 3-5 become Pro Bowlers in the future. It will be years before we can properly and fairly judge the trade (that last part wasn't directed at you, Grahamburn, more towards comments elsewhere about the RGIII trade that seemed germane to this thread in general and the immediate discussion specifically).
