For a player to be overrated or underrated, he must be rated first.
This seems obvious, but it's worth stating to San Francisco 49ers fans who come across this article.
I perceived how 49ers offseason additions have been rated by reading comments sections and other writers' opinions. From there, I formed an opinion on the following five players.
"Overrated" players aren't necessarily bad additions. And "underrated" additions aren't necessarily going to make a huge difference this season.
I'm simply providing my expectations for five players I believe many 49ers fans and scribes have rated inaccurately.
