For the most part, the San Francisco 49ers addressed all of their major weaknesses this offseason.
Especially on offense—they gave it an overhaul. And it needed an overhaul. It was slow as molasses in more ways than one the past few years. Now, it might be one of the faster offenses in the league. Opposing defenses won’t know what to expect. The Niners offense will be totally different.
The defense should be similar—it’s still a 3-4. But it lost a couple of starting corners, a couple of starting linebackers and a couple of starting defensive ends.
