For those in opposition of public money towards the construction of a Vikings stadium, Ted Mondale -- the chairman of the Metropolitan Sports Facilities Commission who is campaigning for a new building -- dug up some figures that disclose that the four pro teams now operating in the Twin Cities have paid more than double in taxes than what local and state governments have paid the teams through public investments in sports venues.

According to documentation provided by Mondale, since 1961, when the Twins and Vikings arrived, the current four pro sports teams in the state have paid $507.9 million in various taxes. In comparison, the public investment in major sports venues over the same period equals only $214.2 million.

The study shows again how much tax money is generated by our pro sports franchises, and what a loss it would be if any of them should leave -- but especially the Vikings, who have generated the most tax revenue of any of the four teams over the past 50 years.

Of course, these figures probably won't interest the geniuses in St. Paul who are only interested in keeping their jobs.

Anybody who knows what an asset the Vikings are to the state would not vote against building a domed stadium, which would only be used by the Vikings only 10-13 times a year but also could be used some 300 days a year for other uses.

According to Mondale, of the tax revenues paid for by the Twins, Vikings, Timberwolves and Wild since 1961, a total of $474 million -- 93.3 percent -- went to the state of Minnesota. The rest went to cities and counties.

Not included in Mondale's $507.9 million figure was tax money contributed by the North Stars, who played here for 26 seasons, from 1967 to 1993, before departing for Dallas.

The Wild, which began playing in the NHL in 2000, has generated $53.1 million in taxes. The Wolves, who entered the NBA in 1989, have generated $11.5 million. The Twins' total tax contribution during their 51 seasons here has been $154 million.

Last but not least, the Vikings have contributed $185.7 million, a big reason why the NFL team deserves a new stadium.

It's also interesting to note that of that $214.2 million figure for public investment, $54 million of that -- 25 percent -- is Hennepin County's $54 million for the construction of Target Field.

The City Minneapolis has contributed $87.5 million, compared to $7 million for St. Paul. The remaining balance includes $55.7 million paid by the state, $8 million paid by the seven-county metro liquor tax and $2 million paid by the Minnesota Ballpark Authority.

Can you imagine how much more the Twins are going to contribute in the coming years now that they have their new ballpark? With a new stadium, the taxes generated by the Vikings would be astronomical compared to what they are paying now at the Metrodome. And if the Wild and Wolves could find a way to win once in a while, their tax figures would climb, too.

This study is just another reason a stadium bill should be passed at this session of the Legislature. It would not only benefit the Vikings but also mean this area could attract another Super Bowl, more NCAA Final Fours and truck pulls, and it would be available to Minnesota citizens year-round the same way the Metrodome is now.
