Seneca Wallace and 49ers' QB picture

The San Francisco 49ers' reported interest in free-agent quarterback Seneca Wallace affirms concerns over the situation behind starter Colin Kaepernick. The team isn't necessarily banking on Colt McCoy, Scott Tolzien and B.J. Daniels.

2008-12 QB Stats as Starter

Wallace, like current 49ers backup Colt McCoy, played under current 49ers offensive assistant coach Eric Mangini in 2010. Mangini was the Cleveland Browns' head coach then.

The chart shows starting stats for Wallace and McCoy since 2008. The numbers are fairly similar. Both players are mobile quarterbacks. McCoy has run the ball on 10.1 percent of action plays, compared to 5.4 percent for Wallace. Wallace has a much better touchdown-to-interception ratio, but McCoy has taken sacks more frequently. Their Total QBR scores are similar and below average -- consistent with what we might expect from projected backups.

Wallace was on the Seattle Seahawks' roster when coach Pete Carroll and general manager John Schneider took over before the 2010 season. They traded Wallace to the Browns for a 2011 conditional pick. Seattle later traded that pick to the Detroit Lions.

Wallace, who recently turned 33, was a fourth-round pick of the Seahawks in 2003. The Browns cut him before last season. Wallace was not on a roster during the 2012 regular season. The New Orleans Saints signed and released him this offseason.
