The 2012 NFL free-agent market is ripe with top-tier talent, and there are sure to be a lot of big-name signings.

With so many free agents up for big paydays, you're sure to hear a lot about the biggest names on the market, but oftentimes, those are the biggest flops while under-the-radar signings that go unnoticed have the biggest impact.

In 2012, there are sure to be plenty of those names to go around. The NFL's elite will surely get their paydays, but there are plenty of respected players that will go unnoticed—that is, until they're making their opponents pay for not paying them.
