Realistically, our receiving corps is a great big bag of unproven outside of Steve Smith (who's old and has been nicked up a lot over the past few years).
I'm not necessarily in the 'need a receiver' crowd because it's a young bunch with some potential. But realistically, a Panthers team that can cut John Kasay can also swap out Steve Smith. Doesn't appear that they will, but stranger things have happened and this offseason I'm not ready to rule anything out.
While under yours, and the right definition, Gettis and LaFell are still unproven....they showed enough last year for me to feel very comfortable in what we have.
