I can see that. The key difference being that he's playing in a league where a lot of those tools are more valuable than ever before.
For years a lot of teams looked for either big offensive numbers, or a nasty streak when evaluating defensemen. They became so fixated on those abilities that they often overlooked the most important one - whether the guy could actually play good defense.
In the last 5-7 years, you've seen a shift in how teams approach defensemen. The "solid, but unspectacular" two-way guys that they tended to take for granted, are now the guys that everyone is looking for. Especially the ones who can really skate.
When we look at the Rangers we see examples of guys who rose (McD, Skjei) and fell with this shift (Staal, Girardi). Granted there were other factors such as injuries. But even without injuries, the skating differences would've had both pairs of players trending in opposite directions, just maybe not quite as noticeably.
