The Chargers released him, days before training camp. Wilhelm was a part-time starter last season after starting 14 games in 2007. He had 68 tackles last season. Wilhelm had 247 tackles in six seasons in San Diego. He became a whipping boy of sorts for fans in San Diego last season as the Chargers suffered on defense.
The timing of the release means he can get a jump on catching on elsewhere before training camp starts.
Burnett, who is very good in pass coverage, and veteran Tim Dobbins will compete for a starting job. Both are expected to play in Ron Rivera's defensive system.
