I would say its an upgrade, but no it isn't a huge one.
Suggs can hit the holes quick, he is a talented guy when put in the right situation. But getting a neckstinger didn't help him out as far as getting into the swing of things.
Green has established himself (okay, not really), but at least enough for me to believe that he is going to see a lot of time. Plus you have to factor in the torrid o line they have.
So really, it depends on the deal, but right now I wouldn't be putting a lot of stock into Suggs.
