Agree on #1, scenario most likely would be for their 1st and 2nd rounders, not both 1st round picks
other than the fact that the lions need a ton of players and so the argument could be made that they would want to keep all of their picks, i think it makes alot of sense for them to trade #20 and #33 and move back up into the low teens and take Andre Smith or Michael Oher to protect their franchise QB. This obviously assuming they draft Stafford #1.
