Yikes indeed, my "surprise" underachieving team this year is the Bears, but the Seahawks are a close second along with the Bengals, if true it does appear the Chargers worked the Seahawks, but that worked out well for the Dolphins via the move back from #12 trade.
I think the plan was to have Hasselback play this year anyway, can't really judge this trade during training camp. Losman does have a lot more game experience than Whitehurst.
