How wil the colts fix the Offensive line?

I read that the Colts have already released Andy Alleman, who was supposed to be a key acquisition to help bulk up the offensive line this year. The line has been pretty bad for the last few years, though manning has made it a habit to get rid of the ball so fast not many notice. With Lilja gone, Pollak and Ugoh close to being considered busts, and Mudd retired, added to the blow up of the plans for alleman, what chance does Indy have of creating holes for running backs this year?
