True, but why did Stone return with a few games left in that season. My take is the original plan that season was to keep him on LTIR until the playoffs but once they dropped in the standings and were at risk of missing the playoffs (which ultimately happened), they scrambled to make moves to be able to take him off LTIR so he could help try to get them in the playoffs. Can I prove it? No, but Stone and Vegas have lost all shred of goodwill with me.
That's exactly the point. You can take a guess as to what was going on, but you can't prove anything. Which, you should know that hypothesize all you want but what matters is what you can prove. By the same token, there was a decent argument that Vegas could have pulled him off LTIR early this season to make sure it locked down a playoff spot ... but, it didn't. Why not? Again, we're left with guessing and speculating without any proof.
Back to 2022: when Stone came off LTIR, Vegas was 2 points out. It had been out of a playoff spot as far back as March 22, so they flirted around with being in/out of the playoffs for 3 weeks before Stone came back. Even with Stone in for those last 9 games, they went 3-2-4 to miss and were eliminated on the 27th - game 81 - when they went to OT against Chicago in what would be their 3rd consecutive SO loss. If they were worried about making the playoffs, you'd think they would have brought Stone back a lot earlier.
That’s the part the NHL isn’t enforcing.
This is the entire point right here. If the NHL knows there's a problem, it's choosing not to enforce the rules that exist. That leaves everyone trying to create "solutions" to "fix" that problem that have all kinds of unintended consequences that they want to ignore because "we're fixing the problem, everyone!" and ignores that the real solution, the simplest solution, is for the league to do its job in the first place.
