The Ravens haven't been consistent in the amount of importance they've placed on the backup quarterback position recently. Baltimore went from having one of the most experienced and expensive backups in Marc Bulger in 2010 to a rookie sixth-round pick in Tyrod Taylor last season. Taylor has completed one pass in three brief appearances. To be fair, this spot has been irrelevant on the Ravens, because Flacco hasn't missed a start in his four-year career (73 starts, including the playoffs) and has proven to be among the most durable quarterbacks in the league. The Ravens added more veteran depth by signing Curtis Painter this offseason, although it's unknown whether he'll beat out Taylor for the No. 2 spot. Painter played last season under new Ravens quarterbacks coach Jim Caldwell in Indianapolis, where he was benched after failing to win in eight starts.
Confidence rating (out of 100) if Flacco goes out for extended period: 18.
