The Minnesota Vikings don't need the Metrodome anymore because the team's going to be moving into a new stadium that's scheduled to open in time for the 2016 season. The thing about the new stadium though is that it's being built on the site of the old stadium, which means the old stadium needs to be torn down.
That process started back in mid-January, when the roof of the Metrodome was deflated. Now that process is on to step two and step two involves the Metrodome being completely destroyed. As you can see below, the Metrodome looks slightly different than it did during the Vikings season finale on Dec. 29. It's a lot less purple.
