The Colts are "optimistic" that NT Brandon McKinney (torn ACL) will be ready for training camp. McKinney tore his ACL last August after signing a two-year contract. Entering his age-30 season, McKinney needs to get on the field as soon as possible to compete for a job. The Colts signed NT Aubrayo Franklin as a free agent this offseason, and they also have 2012 fifth-round pick Josh Chapman waiting in the wings.
