Games involving the Baltimore Ravens often produce the AFC defensive player of the week.  For Week 15, the award went to a former Raven, in a game played against the Ravens.

Chargers linebacker Antwan Barnes, who spent the first three years of his career in Baltimore, chalked up four sacks against the Ravens on Sunday night, in San Diego’s 34-14 Sunday night win.

Barnes, who had no starts in five prior seasons, has started four times in 2011.  But he came off the bench against Baltimore to notch his career-high quartet of sacks.

For the year, Barnes has 11 sacks — fourth most in the AFC.
