Yeah, I don't see service time or super two status being a big deal in any decisions regarding Watkins. His most likely role is that of super sub - not a guy that causes any roster decision worries.
Watkins could probably stick as a average to below-average 2B in my opinion. He probably wouldn't have a problem putting an OPS around .700 which is average for that position, and his defense is fine. I think people pigeon-hole Watkins as a supersub just because he COULD fill that role, even when he could do more.
