Chris Mason is eligible to become an unrestricted free agent this summer. Pekka Rinne will be coming off of hip surgery, so the Predators may want to retain the services of a veteran like Mason. However, they could also choose to promote Magnus Hellberg from the minors to serve as Rinne's understudy. Mason didn't look very good when he did play in 2013, so it would make sense if he were let go.
