Dennis Allen said that the Saints are considering a quarterback switch.

A decision hasn't been made on who will start against the Rams.

Allen thinks we need to look at everything. We need to look at everything. As we prepare for the Rams, we will go through that process.

Allen said the starting job was contingent on the offense continuing to perform well. In their last two losses, the Saints scored only 23 total points.

Allen said that they haven't been doing as well recently. We have to evaluate that. I believe that we need to look at that.

When he injured his back in Week 1 he couldn't play the rest of the season. Allen initially satWinston for the game against the Minnesota Vikings in London to allow him to heal, but eventually decided to go with Dalton full time.

Allen said at the time of the switch that he was healthy enough to play, and he eventually was not on the injury report, but admitted it was unlikely that he would be 100%. His decision will be influenced by the health of the man.

Allen said that they might have to visit with him or the medical staff. I don't know if Jameis will be healthy this season. He's in here every day and working with the trainers to get himself ready. I think he's close to being there.

The health of the offensive line is one of the factors. The starting center and right guard for the Saints, Andrus Peat, did not play this weekend due to injury. The Saints were forced to use backup guards Calvin Throckmorton and Lewis Kidd and backup center Josh Andrews after starting left tackle James Hurst left the game with a concussion.

Allen thinks everything goes into the decision No decisions are made in a vacuum. We have to do what we think gives our team the best chance to win. It will come down to that.
