A couple quarterback notes of interest

Some NFC West quarterback stats of interest as Week 10 approaches:

San Francisco 49ers quarterback Alex Smith is completing 74.2 percent of his passes when not under duress or getting hit.

That figure ranks second in the NFL among the 33 quarterbacks with enough attempts to qualify. Those passes traveled 8.0 yards past the line of scrimmage on average, close to the 8.3-yard average for those 33 quarterbacks.

The first chart ranks NFC West quarterbacks by NFL passer rating in these situations. I did not use the Total QBR metric because eliminating sacks from the equation skews the totals.

As the second chart shows, Smith is completing a league-low 21.1 percent of his passes when under duress or getting hit. The rate is 41.1 for the 32 other quarterbacks with enough attempts to qualify for consideration.

Smith avoids mistakes in these situations. That is good. He has taken more sacks than any other quarterback since the 2011 season began, however. Converting some of those into incomplete passes or positive plays would mark progress. But because he avoids disaster in these situations, his NFL passer rating works out to 57.1, which ranks 12th in the NFL.
