Video: 49ers rookie Ian Williams on OTL

Outside The Lines followed Notre Dame nose tackle Ian Williams through the post-draft signing process right up to his arrival at San Francisco 49ers headquarters.

Through Williams, we see the highs and lows players experience as they chase their NFL dreams after going undrafted. We hear Jim Tomsula, the 49ers' defensive line coach, recruiting Williams to the 49ers and welcoming him to the team.

Cue the video.
