I think some of it is just novelty at this point. We've had some OK (Lucroy) to bad defenders for quite some time, so a defensive whiz is kind of exciting, but considering Lucroy is pretty strong at framing and OK to slightly above in others Martin would have to hit pretty well to take a lot of time away. There is a solid argument that he and Kottaras offer similar value, and trying to swap one of them for something else is solid, but you would probably want to figure out how to get another power threat off the bench if that is the case.
