The San Francisco 49ers have generally used bigger linebackers in their 3-4. It likely will impact who the team is looking at in the 2015 NFL Draft.
The San Francisco 49ers could head into the 2015 season feeling fairly comfortable with their short term pass rush depth. They have Aldon Smith, Aaron Lynch and Ahmad Brooks, all of whom can get after the quarterback. They could use more depth at OLB, but not so much that it is a problem in 2015.
However, over the long term there are plenty of question marks.
