A team as barren in the pick/prospect pool as we are should probably start to think about cashing out on guys like Rust and Dumo before they fall off a cliff or are up for raises too rich for us. But I don't see the team doing it. They'd rather let those guys walk, imo, than to worry about cashing out and replacing them.
Though I do think Hyman's a really solid replacement. Not age-wise, but in terms of production and style. If you swap Rust for Hyman, I don't know that you'd really notice much of a difference and you'd get a nice return. But again, this team's not that cutthroat or forward thinking, and it won't happen, so this is all just kicking around ideas.
