Would you trade Matt Forte for Calvin Johnson?

In fantasy football, i'm thinking about doing this trade. I have Matt Forte, and i'm thinking about trading him for Calvin Johnson. I have pretty good receivers and running backs, so I don't necessarily need one position more than the other. Matt Forte's inconsistency really bugs me, and even though Calvin Johnson has put up less fantasy points this year, I feel like he's more of a sure thing to get the job done each and every week. Is this a good trade for me in your opinion?
