DetroitLions.com mentions RE Kyle Vanden Bosch as a candidate for release. Vanden Bosch, 34, has one year left on his deal, and it carries a $10.7 million cap hit. That's far too much for an aging end who recorded just 3.5 sacks in 2012. The Detroit defense could look a lot different in 2013, as they have 12 players set for free agency and a couple others as potential cap casualties.
