PHOENIX -- The 49ers are a new team on offense under Mike Singletary. They made that clear in how they approached the Monday night game against Arizona.

I'll make available the full personnel breakdown after passing along Ken Whisenhunt's take on how the 49ers changed from Week 1 to Monday night.

Whisenhunt on the 49ers' offense: "There was a lot more quick game, a lot more of the power scheme trying to run the football. And they got the ball out quick, which when we played them the first time, there wasn't as much of that. It was a different offense and we anticipated that because of the quarterback and because of what they were trying to get done."

These changes didn't necessarily show up in the 49ers' personnel use or run-pass ratio. For example, San Francisco ran the ball on eight of its first 12 plays against Arizona in Week 1. The 49ers ran the ball on their first five plays and seven of their first 10 Monday night. They wanted to get Frank Gore involved both times.

In looking at first-down plays, the 49ers ran on their first six Monday night. They then called eight passes in their next nine first-down plays spanning the second and third quarters, completing only one of these passes (for 8 yards). A defense can dictate play selection to a degree, but I'm not sure what was at work there. The 49ers were leading the game, so there was no obvious need to throw in those situations.

The 49ers use tight ends as fullbacks sometimes. They also run a variation of the Wildcat periodically. I counted the tight ends as tight ends, regardless of where they lined up. That's a general rule I follow when charting personnel. The thought is that defenses tend to match the personnel they see in the offensive huddle.

The full personnel breakdown is available for download here. The file includes one sheet with play-by-play information sortable by down, distance, yard line, personnel, play type, yards gained and more. Another sheet shows production summaries across personnel groups. The file does not cover quarterback spikes or aborted plays. Quarterback scrambles count in total plays but not in rushing plays. And sacks do not figure into pass attempts.
