It's nearly impossible for Stafford to fall that far, Sanchez I wouldn't want to trust my franchise that went 0-16 to and Freeman will have a big chance of even being there at Round 2 Pick 1, so that would be an option.
I bet they want a franchise QB and I really hope they get somewhat competitive. I'll go with the popular picks and say they go for Stafford at 1 and an O-lineman at 20.
If they do see something in Orlovsky, they might aswell go LB or so with their first pick and O-line with the 20th. Everyone's stressing their offense, but if they get a decend O-line, they're an ok team on the offensive side of the ball. A good RB, a mediocre QB at best, an amazing WR and a good O-line would get them to at least .500 if the defense can do their thing.
