It's tempting to think that the only players who leave a team in the offseason are its free agents.
But that's just not true, especially for a salary cap-crippled team like the Detroit Lions. It is true that the Lions have a good chunk of their roster set to enter free agency this offseason, though, and you can see what my determinations are for those players right here.
But what about everyone else? Just being signed to a contract through 2013 is hardly any proof that a guy will actually still be on the roster come August.
Simply put, there are some guys on the roster that the Lions might not mind parting with. In many cases, the money doesn't match the output, and the Lions need to be very concerned with matching money to output this year, especially considering how underwhelming their 2012 season was.
So who on the Lions' roster is safe, and who is, shall way say, is vulnerable to change?
