Defensive line is a position of particular note for 49ers fans. The nose tackle position remains a question mark with Isaac Sopoaga and Ricky Jean Francois both up for free agency. They've got Ian Williams and Will Tukuafu coming back next year, but we don't really know what they think of Williams in his development. Ice is a short term option if they have developmental ideas, while RJF's size leaves his future role up for debate. He has generally come across better as a rotational defensive lineman at most of the positions, as opposed to a full-time nose tackle.

Defensive end is another significant area. The team eventually needs to find a replacement for Justin Smith, but in the meantime, they need additional depth to spell Smith and Ray McDonald. Demarcus Dobbs could work his way into more time this offseason, but they still likely will be looking for another body.
