Super Bowl XLIX belongs to Kansas City if voters approve several hundreds of millions of dollars worth of taxes next month. That was the message from NFL commissioner Paul Tagliabue on Sunday. The NFL had already expressed interest in giving Kansas City a Super Bowl and yesterday they added a date: 2015.

However, the NFL won’t award the Super Bowl to Kansas City if fans have to sit out in the cold. For that reason, they’re demanding that a roof be built on Arrowhead Stadium. The NFL is also asking for some improvements to the stadium.

Both of those requirements could be filled if Jackson County voters pass two initiatives on the April 4 ballot, which would pay for the improvements and rolling roof. The roof would be used by both the Chiefs and Royals.

Expected cost for the two projects are expected to reach $777 million.

Listen below to audio from Tagliabue, Chiefs President Carl Peterson and Chiefs owner Lamar Hunt.
