INDIANAPOLIS -- Colts quarterback Andrew Luck is ready for the start of the regular season based off his individual stats.

He was 21-of-26 for 205 yards passing in limited action.

The same can’t be said about the overall first-team offense. The unit didn’t score a touchdown in the seven offensive series that Luck was on the field in the preseason. They had to settle for two Adam Vinatieri field goals.

“That is the goal, to just go out and execute, be efficient, move the ball down the field and finish with touchdowns,” coach Chuck Pagano said. “We are going to keep working and keep practicing. I’m not going to lie to you and tell you that everything is going to be OK. We have to execute, we have to communicate, we have to make plays and we have to put the ball in the end zone.”

The inability to score touchdowns with the starters is concerning, especially when you consider that the Colts reached Baltimore and Philadelphia’s half of the field five times.

It’s even more concerning when you consider the offense will likely have to carry the Colts this season as their defense still has a number of question marks.

“I know we’re going to score a lot of points with this offense,” Luck said. “We’ve got guys that can get the ball in the end zone.”

The inability to score touchdowns is just the start of the Colts’ offensive problems. Frank Gore was purposely limited in the preseason, but they haven’t shown any signs of finally be able to run the ball. Non-quarterbacks have rushed for 102 yards on 54 carries in the preseason.

The offensive line didn’t help in run or pass blocking. That group gave up three sacks and six other quarterback hits in just one half against the Eagles. And to make matters worse, starting right tackle Joe Reitz is dealing with a back problem and left guard Jack Mewhort is out 2-4 weeks with a knee injury.

None of the Colts' key players are expected to play in the preseason finale at Cincinnati on Thursday.

“I think we’re right where we need to be and by no means are we perfect,” Luck said. “We still have a lot of work to do and we’ll keep grinding.”
