The St. Louis Rams landed the prize free agent blocker of 2009 Friday by reaching an agreement in principle with Ravens center Jason Brown.

According to a source, Brown received a five-year, $37.5 million contract that includes $20 million in guarantees. He will earn $24 million over the first two years of his contract. Brown's agents, Harold Lewis and Kevin Omell, spent Friday night working on the final language of the contract before having Brown sign the deal.
