Last year, the Vikings replaced the turf at the Metrodome because the old stuff led to too many twisted ankles and torn ligaments. There was a whole to-do, and it went to court, and eventually they were allowed to bring in the new turf. It lasted all of one season.
Because of the spectacular dome collapse in December, the turf has gotten all moldy and gross and needs to be replaced, and apparently they weren't expecting the lockout to ever end, because they're only getting around to this now.
And to make sure the new turf is the safest and strongest and best it can be...the Vikings awarded the contract to the lowest bidder.
