Most of the big names hitting NFL free agency aren't big stars anymore.

While Ed Reed is coming off a Super Bowl season in Baltimore and Wes Welker catches 100 passes every year, this crop is more about aging defensive players such as Charles Woodson, Brian Urlacher and Ronde Barber.

When full free agency begins Tuesday at 4 p.m. EDT, with all 32 teams under the $123 million salary cap, the bidding wars might be furious for a while. Or perhaps not, considering the dangers of signing players beyond their peak years to rich deals that can hamstring teams financially in the future.
