I think Sully's time is up, and I think his constant issues with correct lineups are a big part of that. I don't think adjustments are an issue with the roster as currently constructed.
Adjustments is such a buzzword around here. What should Sully have adjusted with regard to the system or approach? He should've benched JJ, absolutely. He should've started Jarry from the hop, absolutely. He should've tried Jake with Geno and Rust and put Zucker up with Sid again, absolutely. But systems-wise? What do you adjust to get a successful outcome out of a team with no third line, a fourth line with zero offensive pressure or potential, a blueline that did f***-all in terms of producing, and a bottom pairing that's arguably the worst combo in the entire league?
Don't get me wrong; I'm done with Sully. If for no other reason than the last several years of his usage of JJ. But suggesting that any other coach could've squeezed blood from this stone isn't right, imo. This roster is severely flawed, and that is why I put the bulk of the blame on JR for the current (and recent) state of this team.
JR's gotta go. If Sully & Co. follow, I'm entirely fine with that too. But JR's proven time and again he's lost the plot and he spends more time trying to undo his own f***-ups than actively improving the team and building upon successes.
