Galian,
I don't think anyone here is really saying that Romo doesn't have trade value. Would it be a risk due to back surgeries and age? Yes, but there would be some teams inquiring about him if it was known that he is on the block.
The whole issue does not really revolve around what other teams would give up, instead it is based on the fact that Dallas can not trade him this soon. It would be an absolutely stupid move for us to trade him due to the dead money.
If Romo comes out and plays good in 2014 with no re-occurring injuries, then that is the time to discuss possible trade options. You are a year too early, maybe two years.
No team is going to give much for an ageing QB coming off injuries with a big contract even though their end doesn't look as bad. Teams may be willing to take on the money but not give up early draft picks to accompany the money. They will want to wait it out one season to see if he holds up. Romo's trade value is low right now and with a good 2014 season, his value will double. There are a lot of question marks surrounding him right now.
There is only one team that would even consider it and that is the Raiders and I don't see that happening.....Palmer may have taught them a lesson. To top everything off, Jerry will not even think about trading away his golden boy, that contract proves that he is all-in with Romo until retirement from age or injury.
