Simon, Calmus boost Colts' defense

Plenty of teams have been actively trying to shape their final 53-man rosters over the past few days, including some potential playoff teams with already strong lineups that are making aggressive moves to bolster certain positions or fill a few remaining needs.

Indianapolis, Minnesota, Seattle and Dallas seem to have made the biggest acquisitions as they try to reach the next level.

Corey Simon Simon

Indy fans and players alike should be very excited about the commitment the ownership and front office made to get the best players possible to fill voids on the roster. The biggest move was the signing of DT Corey Simon to bolster the defense. This gives them another potential Pro Bowl player up front to team with DE Dwight Freeney.
