You called it: Which rookie free agents will stick?

Posted by ESPN.com's Mike Sando

NFC West teams have signed 42 undrafted free agents in preparation for post-draft minicamps beginning Friday.

Twenty-one play offense. Twenty-one play defense. Six come from the Big 12 Conference. Five come from the Big Ten, five from the SEC, four from the ACC and four from the Mountain West.

Great, but which ones will earn roster spots when NFL rules force teams to reduce rosters to 53 players Sept. 5? You tell me. I'll track the predictions made in the comments section of this item and shower praise upon the enlightened.

The chart shows how many undrafted rookies each NFC West team is carrying out of the total number of players at each position. For example, two of the Cardinals' 10 receivers are undrafted rookies. Zero of the Seahawks' 11 receivers are undrafted rookies. And so on.

Seattle is carrying nine linebackers, even with Leroy Hill on the roster. Two of the seven -- Mississippi's Tony Fein and Maryland's Dave Philistin -- are rookie free agents. Three others -- Lance Lawry, D.D. Lewis and David Hawthorne -- were not drafted.

The Rams have five undrafted rookie offensive linemen. They have 16 offensive linemen overall. Jason Smith, Jason Brown, Jacob Bell, Richie Incognito, Alex Barron and John Greco will presumably earn roster spots. Adam Goldberg and Mark Setterstrom could also be favorites. The team would likely keep a ninth offensive lineman. Roy Schuening? Or perhaps one of the rookies?

Also: I've updated the 26-column NFC West rosters to reflect the 49ers' rookie free agents and Hill's new deal with Seattle. Download here. I also added two sheets breaking down the rookie free agents in greater detail (cheat sheets for predicting which ones might stick).

Heads up: The Rams released quarterback Jeff Otis, giving them four quarterbacks. Defensive tackle Michael Marquardt was also released.
