Demetric Evans left the Bay Area Wednesday morning. By the end of the day, he had agreed to terms with the 49ers. Evans (6-4, 284) is listed as a defensive tackle but he actually ended up playing a lot of defensive end for the Redskins last season when Phillip Daniels went down with an injury this past season. The Redskins wanted to retain Evans, but as is usually the case in Washington, the team didn't have enough room under the salary cap to do so. Look for Evans to challenge last year's first-round pick, Kentwan Balmer, for the starting spot at left defensive end and for Isaac Sopoaga to slide inside to nose tackle.
When it comes to free agency, the 49ers closely study teams that don't have a lot of room under the salary cap. The theory is that those teams often have to give up better players than the ones being discarded by teams with cap space. As a result, the 49ers' often are studying up on the Redskins' roster. Perhaps the best example of this is Walt Harris, who was acquired in free agency after the Redskins released him in 2006.
By the way, I'm watching the classic 49ers-Packers "The Catch II" playoff game on NFL Network. Don't tell me how it turns out ...
