Colts rookie quarterback Andrew Luck shouldered his heaviest throwing load of camp after Saturday's rain-shortened work. He completed 28-of-41 passes with no interceptions and at least five touchdowns. Considering the restriction on defensive players to not bring receivers to the ground, it's difficult to determine whether a receiver might have scored on certain plays. Overall, Luck wasn't at his sharpest. A few of his passes were uncharacteristically off target. Source: Indianapolis Star
