Arguing or debating Jarvis Jones is kind of moot at this point.
There's plenty of time to say "I told you so" when his career here is done. What's the point now? Let him play it out. I'm still unsure what he's going to become so why not just say "who knows" and wait and see another 16, 32 or 48 games?
There isn't really a "decision" to be made about Jones right now. He's the starter. He's going to make the roster. I guess if you really have given up on him, you might put OLB/edge defender higher on your "needs" heading into this draft, but I think we can all admit the Steelers probably aren't artificially pushing up OLB's on thier draft board like they may be with CB, ILB, DE or WR. And OLB (even if you don't think Jones will cut it) is still probably behind those other positions on need.
The only fair thing we can do now is collect more information on Jones and continue to be non-biased in our evaluation of him.
