Awesome, I was hoping you would say that first part of your statement. Allow me to go through my opinion..
Jones will always be a great skater and look like he's doing the right thing most of the time. However, especially during the Nashville game (and I realize everyone was awful outside of Korpi, just hear me out.) he made a play where the forechecker was coming at him, so he turned around and through it off the boards behind the net, the puck bounced off and went right to a Pred.
Another moment, he was skating through the NZ with the puck, got into the zone (because of his great skating) and fell once he got in, this then set up an odd man rush.
Again these are just two examples from the same game (there are many others). But not too long ago he and Dubinsky got caught puck watching on a last minute powerplay against the Rangers, and Stepan got a SH breakaway goal because of this. These are typical mistakes by young Dmen, and that's fine in this awful season, but it just makes my point that he's struggled mightily and has not been the same player he was in January when he got here, when he was fantastic.
Now I realize you're going to poo-poo these observations due to no video support. And that's fine, it is after all my 'uneducated' opinion. But other than his points totals (which are good), what has he done recently as a defenseman that warrant your huge praise?
If you post that, I might respond in a PM since we're just flooding the GDT with our conversation.
