Who is the most important player on the 49ers this season?

I say Justin Smith is the most important player on the 49ers this season. He is the engine that makes that defense go. The 49ers’ defense was terrible without Justin Smith last season, and until Michael Crabtree is 100-percent healthy, the 49ers are going to have to win games with their defense.

Who do you think is the most important player on the 49ers this season and why?
