DE Ronald Blair
Re-signing Blair to a one-year deal didn’t make a ton of waves for the 49ers this offseason. The backup defensive end tore his ACL in Week 10 and missed the rest of the year. While Blair doesn’t start, he’s a very valuable piece for a defensive line that relies heavily on its depth to make life difficult for quarterbacks for 60 minutes. Blair had 3.0 sacks in nine games last year, and 5.5 in 16 games the year prior. He was also No. 7 in PFF’s overall defensive grade for the 49ers. Blair rushes the passer effectively and plays the run well. He’s not liable to work into a starting job or play a lion’s share of the snaps, but his role is still a valuable one for San Francisco.
