With renovations at Kinnick Stadium complete, University of Iowa officials are looking indoors for more improvements. The Hawkeye football team's indoor practice facility -- more commonly known as "the bubble" -- has been around for more than 20 years. Officials believe it needs to either be replaced with a more permanent structure or upgraded. Iowa Athletics Director Gary Barta says building a new indoor football practice facility is high on his to-do list, though plans are still in their preliminary stages. Barta says improvements to the Jacobson Athletic Complex, which houses the football coaches' offices, the strength and conditioning facilities, the team's meeting rooms and the locker rooms, is also on the to-do list.
