No, it's nothing like it. Mark Stone wasn't signed to go on LTIR. He was signed to play. He's a star player; not a redundant depth piece. He was established on his team, and knew the systems, coach, and players. He played in every season, and has never spent a full season on LTIR, or spent 14 months out with a major, career-threatening injury to then come back for just the playoffs.
He's gotten injured in season for a couple months, and then Vegas has utilized the no cap in playoffs loophole and massaged timelines to use his significant cap space to add at the deadline. What you're advocating for is something very different, and it would be a massive concern if our GM thought that was a good move. Living in LTIR space out of necessity due to permanent injury of a roster player is also very different than living in it out of some weird choice.
