Each year, we like to run a series of posts called "90-in-90." The idea is that we'll take a look at every player on the roster, from the very bottom to the top and break them down a few ways. This roster will certainly change, and some days we'll have more than one so it's not exactly 90 players in 90 days. At this point, it's a name we're keeping around for street cred.

This past May, the San Francisco 49ers signed New Mexico center Dillon Farrell as an undrafted free agent. Farrell played center the last two seasons, and also in 2010. In 2011, Farrell played right tackle, and has indicated he can play all five positions.

You can read over some scouting reports at NFL.com and DraftInsider. He's a guy who has the size to play in the NFL, but the scouting reports seem to indicate technique is an area he needs to improve. Getting to work with Mike Solari will hopefully help him in that regard.

Expected 2014 impact:

Farrell faces an uphill battle given the 49ers depth along the offensive line. Alex Boone's holdout helps everybody competing for a roster spot, and Farrell likely will need every boost he can get to earn a roster spot. I suspect he has a good chance of earning a practice squad spot. If he somehow made the roster in 2014, he would likely be an inactive every week, similar to Joe Looney in 2012. However, the practice squad is likely the most we can expect from him.

Odds of making the roster:

As detailed above, the chances are slim. Alex Boone's holdout means other offensive linemen will rise up a bit, but barring a trade, Boone will likely be back at some point this season to get his accrued year. Farrell has been playing right tackle, but I'd imagine his versatility provides his best chance at sticking around the team in some form or fashion. At tackle, he is behind Joe Staley, Anthony Davis, and Jonathan Martin.

More than likely he is also behind Carter Bykowski and Ryan Seymour, so he's got his work cut out for him. Bykowski and Seymour also have practice squad eligibility. Seymour can play tackle and guard, while Bykowski seems to be focused on tackle for now. If none of those three (Farrell, Bykowski, Seymour) make the 53-man roster, they are probably competing for no more than two practice squad spots, along with Fou Fonoti and Al Netter.
