Brent - I think the real issue people have is that the trade doesn't tangibly give you any value. Backup QB's add zero value outside of bye weeks. Todd drafted WR, WR, WR the first 3 rounds which naturally created an imbalance for him at RB. That trade would allow him to re-balance his team without sacrificing any of the strength he already has.
That's what makes trading complicated. I offered a group of guys to Dinny for Brees in attempt to trade my bench strength for a serious need. He wants a legit RB1 or WR1 [as well he should]. I need to seriously think about whether I want to do that or not - I drafted this year with QB as a low priority, but if I trade away a WR1, I'm essentially negating my draft strategy.
