COLTS CAMP JON HARRISON No. 6. RIGHT GUARD BATTLE Former starting center Jon Harrison has been the leader in the clubhouse all spring. But incumbent starter Hugh Thornton has yet to tee off.

Others who appear to be in the mix include Denzelle Good and, potentially, rookie Joe Haeg. No. 7 CAMERA READY ADAM VINATIERI 14 | DISCOVER VisitAndersonMadisonCounty.com Don’t forget your camera, because you never know what or who you might see during training camp. There are plenty of great opportunities to snap pictures of your favorite players. Just remember to be courteous to fellow visitors by staying out of their sightlines. Also understand that players won’t be able to stop and take individual photos with you. But have your camera at the ready should they stop nearby to sign autographs so you can prove to all your friends that Andrew Luck's signature is legit.
