Roster snapshot as rookie camps approach

NFC West teams are filling out their rosters toward the 90-player limit as rookie minicamps approach Friday.

2013 NFC West Roster Counts (May 9)

The chart shows where teams stand at various position groups.

The St. Louis Rams announced the signing of 22 undrafted rookie free agents. The team still has nine roster spots open by my count, but the Rams are far from short-handed. They have 29 players scheduled to participate in their rookie camp on a tryout basis, the assumption being that several will earn roster spots.

Some of the numbers in the defensive front sevens can shift based on how outside linebackers and defensive ends are classified. We'll tweak those as roles become clearer.

I'm still in the process of collecting dates of birth and other vitals for the hundreds of draft choices and undrafted rookies joining rosters over the past few weeks. Once those are verified, we'll make sense of the information.

Note that the Seahawks could consider making a roster move involving Greg Scruggs. The defensive lineman suffered a torn anterior cruciate ligament before the draft. He's undergoing surgery this week and could miss the 2013 season.

The 49ers appear to be carrying a high number of running backs, but there is some explanation in order.

Fourth-round rookie Marcus Lattimore counts among the nine players listed at running back, but he's unlikely to play before 2014 while recovering from knee surgery. San Francisco is heavy on fullbacks with Bruce Miller, Anthony Dixon and Alex Debniak. Defensive lineman Will Tukuafu also plays fullback at times. MarQueis Gray, a former quarterback at Minnesota, projects as a tight end/H-back.
