Totally agree with your entire post. I guess I would liken Peters to a TV, would you rather spend $800 on a no-name tv (late first round draft pick) and pray for the best, or would you spend $2,000 for a top of the line TV (Peters) you know will be a great product?
I guess the only thing I didn't agree with was draft position selection affecting trade value, but that wasn't Tim's opinion, it was what he reported teams are looking at. As I said, would Peyton Manning be worth more on the trade block than Tom Brady? Both are elite QBs with Super Bowl rings, but should Brady's stock be less as he was a 6th round pick?
I don't think Peters being undrafted should affect his value, the guy is a rare elite tackle when he's at his best.
