Bellichick traded away two decent quarterback prospects maybe we could have given them AJ Derby back.  Realistically, what do you think we could get for Siemian?  Or who would be foolish enough to give us anything?
You know what Elway's fantasy is of course, to get Andrew Luck.  He would sell his soul to the devil to get Luck even if he has two broken arms and couldn't play for five years.
