The Colts don't have much time to find a solution to the problem.
They travel to San Francisco this week to meet the defending NFC champions, and the 49ers (1-1) are likely to be in a surly mood after suffering a 29-3 loss against rival Seattle on Sunday night.
Luck conceded the loss to the Dolphins stung. But he said Indianapolis doesn't have time to continue feeling miserable.
"We realize we can't go back and do anything about it," he said. "They won fair and square. You can't complain about it. You can't say you got cheated or robbed or what have you. We realize we've got a lot of work to do. We looked at it, saw our mistakes, cleaned a few up (Monday) and hopefully fundamentally we'll continue to get better. You'd love to win, but we didn't. So move on to the next one."
