He is 6-5, 323 pounds and he's only 26 years old, but consistency certainly has been an issue. Rachal started 15 games in 2009 and 14 in 2010, but he was replaced on the 49ers' starting offensive line this past season. The former second-round pick has some upside. He was ranked by Pro Football Focus as the top run-blocking guard in 2010, and he's currently ranked by Pro Football Talk as the top remaining free agent guard available. However, it's difficult to imagine Ravens coach John Harbaugh advocating the addition of a player that his brother, Jim, demoted from the starting lineup because of his penchant for committing penalties. Rachal has already visited the Rams.
