It may be eventually. Depends on who bids on it. the Big Ten doesn't just say "we want a tournament here." The sites put in bids.
The basketball tournaments have been played in Indianapolis for several years and that is hardly neutral from the thought that Purdue and IU are within commuting distance but only Indy and Chicago have ever bid on the games.
BTW, Indy and Chicago really are pretty neutral for those tournaments as ticket allocation is what makes then neutral, not location.
