The draft is not a sure thing. You don't trade proven players for Picks unless you are sure they have nothing left to offer you. This team is a quality offensive line and better offensive play calling away from being a contender and you want to trade all of our good pieces for picks??
What makes you think the 3rd rounder we would get for Dez would be better than Dez?
What makes you think the 3rd Rounder we would get for Witten would be better than Witten?
What makes you think the 2nd Rounder we would get for Ware would be better than Ware?
Look at this teams draft history.. We have years where only 1 or 2 guys end up even being a part of this team in any real way..
Only guy that I could ever see us Trading for a pick would be Romo if we chose to go in another direction I suppose you would trade him for a 1st and a 4th or something and go young at the position.. This isn't something I would want to do but if management decided they wanted to go another direction we would have no choice.
