A sense of normalcy has returned to the Indianapolis Colts’ Northwestside complex. Nearly 95 percent of 2012 season-ticket holders, estimated at 57,000, have renewed their orders. That’s a return to the standard Peyton Manning-era renewal rate after the team experienced a noticeable and anticipated dip — approximately 87 percent renewals — last offseason in the wake of the tumultuous 2011 season and subsequent roster purge. “You never take anything for granted. It’s positive to see the renewal rate so high,” chief operating officer Pete Ward said. “It mirrors what we had done for the last decade for the most part.” The team also has sold all 141 suites at Lucas Oil Stadium. The Colts mounted an immediate bounce-back season in 2012, posting an 11-5 record and earning a wild-card playoff berth after enduring a 2-14 finish the previous season. Approximately 5,500 seats remain unsold as season-ticket packages and won’t be put on sale until after the NFL announces the 2013 schedule Tuesday. The Colts open the preseason the week of Aug. 8-11 at home against Buffalo before an Aug. 18 prime-time visit to the New York Giants. The team has scheduled a season-ticket event in conjunction with a June 12 mandatory minicamp practice at Lucas Oil Stadium. Existing season-ticket holders will be able to change their seats to available locations while perspective customers also can scout out the available seats.
