Lose their QB for the season to an ACL, so trade a 1st round pick for a mediocre at best and injury prone QB with two ACL reconstructions of his own in his NFL career.
Good luck with that.
Will be interesting to see how Bradford takes to Norv Turner's offense, but I expect they just need him to do what Bridgewater did, which is hand it to 28 and manage a conservative passing game. Shaun Hill could have done that.
But this has all the markings of ending badly for the Vikings, as it has for every team that has attempted to navigate this road.
