I'm sorry, but that excuse fails the "too f'in bad" test. Why can't their equipment guys head back to NJ today, pack up the cold weather gear, and get it to Minnesota by the end of the day or tomorrow morning at worst???
Since when did "NFL" stand for "No Fowl-Weather League"?
? Why not just drop by the local sporting goods store in MPLS? The average store there is likely to have a better selection of cold weather gear than any store in NJ. I bet either the Vikings or UofM staff would direct them to a decent shop.
But you are right, lack of long-johns is not a realistic excuse.
