Personally, I don't think Romo would return much in a trade, and that is due to his injury history, his very present disc issue in his low back that will always be there, and his age. I can't see any chance of getting a first for him. I think the best would be a fourth that could become a third if certain benchmarks are met.
And as for Theismann, here's a funny story from the 1997 NFL Draft. During the late portion of the draft, a conversation was held about Keyshawn Johnson writing his book, Just Throw Me The Damn Ball!, and his criticism of Wayne Chrebet. The discussion centered around whether the Jet locker room was going to be fractured over what Johnson wrote. Johnson was a guest during the draft, and it got somewhat heated. After he signed off, Theismann went off on a soliloquy about how Johnson was going to ruin the Jets, and was too selfish of a player and likely hated in the locker room, and would never be a leader of the team.
Chris Mortensen then chimed in and said, "Well Joe, your teammates didn't like you very much, but you were a leader of the team."
Theismann looked like someone punched him in the stomach. After the draft ended, my brother and I were able to go up to the ESPN set and shake hands and talk with Mel Kiper, Chris Berman and Theismann. My brother said that Mortensen was a little rough, huh Joe? Theismann nearly had an aneurysm over it. He said very loudly, "MY TEAMMATES LOVED ME!!!"
Classic.
