Analysis:

Ballard will become an unrestricted free agent this summer and could be headed for retirement for health reasons, as he's been diagnosed with five concussions in the last five years alone. At 32 years old, Ballard isn't completely over the hill, but his lengthy history of head injuries probably ensures that he'll receive limited interest from other clubs.
