Coach Ken Whisenhunt is not expected to name a starting quarterback until Wednesday, but it would be a surprise if he doesn't promote rookie Max Hall into the job.
Starter Derek Anderson has completed only 51.8 percent of his passes this season and has more interceptions (five) than touchdowns (three). What's worse is that Anderson has failed to convert on big-play opportunities in each game.
He's had receivers open for long gains every week, but hasn't been able to hit on a high enough percentage of those plays.
While Whisenhunt said he wants to think about the decision after watching video, he continually has mentioned Anderson missing on potential big plays.
There are inherent dangers in starting a rookie quarterback, particularly one who was undrafted. But ultimately, Whisenhunt has to ask himself if his team would be worse off with Hall.
It's one thing to watch a sixth-year veteran make those mistakes. Anderson is not likely to improve. It's quite another to watch a rookie make them. At least Hall has the potential to improve.
Plus, the Cardinals need to find out about Hall this season. The third quarterback on the roster is another rookie, John Skelton.
If Hall can't play, the Cardinals will have a dire need at the position entering 2011.
Whisenhunt faced many questions about the position on Monday, including if the Cardinals might sign a free agent.
"I haven't even thought about that," Whisenhunt said. "So if you guys can convince Kurt (Warner) to come back, we'll consider it."
The Cardinals gained just 124 yards on offense against the Chargers and only 23 in the second half. They had minus 12 yards in the third quarter, and backup quarterback Max Hall was sacked six times.
"We didn't get the job done," said guard Alan Faneca.
