The San Francisco 49ers are feverishly working on their big board for this week's NFL Draft. While the 49ers are in the middle of a re-tool of the roster due to a number of losses at key positions both on offense and defense, one position they're not expected to address in the selection process is quarterback.

Yes, for the 49ers, their first-round pick might be the easiest to make. Rarely do things work out so well for a team in the middle of the first round. Of course, there’s the rest of the draft and six other starter-caliber players who need to be picked.

From Shemar Stewart to Mykel Williams to Walter Nolen, it looks like the 49ers are staying in the defensive trenches with their first pick.
