Wow, snark much? You assume McCoy is even on the team next year. That's cute. As you said, he's 30, has a high contract and will start to decline before you know it. His "potential replacement" isn't on the roster for a reason. RBs have a shorter shelf life thank a carton of milk.
But hey, at least your reply was so cutting and original. You managed a reading comprehension quip. You must be at the top of your 9th grade class.
