By Jeremy Giggy | Sports Director, White River BroadcastingThe Indianapolis Colts continued shaping their roster this week with another training camp transaction, signing rookie cornerback Mekhi Rodgers while waiving injured cornerback Cameron Mitchell. His performance there earned another opportunity, and now he’ll have the chance to prove himself throughout the remainder of training camp. Training camp provides the perfect opportunity for players like Rodgers to make an impression. Roster changes are never easy, especially during training camp when players spend months competing for opportunities. The next several weeks will determine whether he can turn a training camp invitation into a spot on an NFL roster.
