The 49ers have the strongest defensive line in the NFL, when healthy.
Without any shadow of a doubt, the most powerful unit on the San Francisco 49ers outfit is the defensive line.
Strengthened with the investments of several first-round NFL Draft picks and backed up by impressive depth that could be competing for starting roles elsewhere, the defensive identity of San Francisco rests on the front four being able to fight its way to the quarterback without needing to rely on blitzing.
