In 2003 the Thunder wanted to reduce the number of home games played at the National Sports Center to seven. The Minnesota Amateur Sports Commission which owns the National Sports Center was not comfortable with the idea so the Thunder decided to look elsewhere. Their three-year lease expired in 2003 leaving them open to search for other facilities for 2004. At the time revenue from the Thunder accounted for less than one percent of the National Sports Center's total revenue.

Fan surveys indicated that they would attend more games if the Thunder played in a more central location. On May 12, 2008, they returned to the National Sports Center with a lease until 2011.
