Advancing conversation on Bradford, 49ers

By Mike Sando

San Francisco 49ers safety Donte Whitner's recent comments complimenting St. Louis Rams quarterback Sam Bradford invites a closer look at some of the dynamics.

I'll start by addressing a couple points made in the comments section of our earlier item.

The chart below ranks the 10 best single-game Total QBR scores by starters against the 49ers during the 2012 regular season. Bradford owns two of the top five. He had a 72.2 QBR score over two games against the 49ers, compared to 46.5 across all other games. That affirms perceptions about Bradford playing a leading role in the Rams' success against San Francisco last season.

The first chart is the same one from the previous item. It compares Bradford's cumulative stats against the 49ers to those for the Seattle Seahawks' Russell Wilson. Wilson owns the highest single-game QBR score against the 49ers, but his overall score suffered from a less productive game against San Francisco in Week 7.

On QBR, 100 is the maximum score and 50 is average. Teams with the higher Total QBR score in a game have gone 1,103-175-2 (.863) since 2008, including 222-33-1 (.869) last season, highlighting the role quarterbacks play in winning. The Rams' 16-13 victory over the 49ers in Week 13 was one exception. Kaepernick actually had a higher QBR score than Bradford for that game, an anomaly we addressed in December.
