As the signing bonus continues to skyrocket for the #1 overall pick while the chance of a bust remains about the same... I think you will find more and more teams willing to take less than the trade value chart's recommendations. We may be the first ones to do it, and get ridiculed for it in the process, but watch everyone that comes after us do the same thing.
The trade value chart is merely a guide, and is certainly not the bible. However, it was devised by JJ over 10 years ago.
Finch makes an excellent point: with the skyrocketing signing bonuses these #1 overalls get, there is certainly a downside to earning the #1 overall slot. So, maybe the #1 overall pick is not as valuable as it once was. (Forgive me if that was not your point)
Still, I'd rather have the #1 overall pick than #22, #29, and #61, and some picks in 2009. But that's just me. There are no sure things, but Dorsey and Long are guys that offenses will have to scheme against. Not sure if a dude at #29 will have that kind of impact.
