Free agent Ronnie Brown worked out for the Patriots this week. Joining Brown were TE Nate Byham, TE Ben Hartsock, and RB Brian Leonard. It's the first we've heard of Brown since the Chargers' season came to a close with a loss to Denver in January. Brown can still be a valuable third-down back, but he's 32. He averaged 3.5 YPC on 45 totes in 2013, reeling in eight passes.
