Unless the city can use the various buildings and facilities afterward it doesn't make a lot of sense.
Atlanta was a good example of needed housing and athletic facilities being used by colleges and universities after the games.
The Olympic stadium became Turner field home of the Braves
The housing village became part of Georgia State Univ which is mostly a communter type school
The swimming and diving venue became part of Georgia Tech
The Basketball venue was taken over by Morehouse College
Centennial Park became part of the downtown landscape
Its seems at least in Atlanta's case it got needed infrastruture improvements as a result.
