Agree 100%. DeBoer should not be involved in the day-to-day of what Sunny Mehta is doing.
What Sunny Mehta is doing should inform what players we trade for, sign, or let go. And what Sunny Mehta is doing should inform whether DeBoer is the right coach at the end of the season. DeBoer should otherwise be doing the same job he's been doing.
I view it like an HR person at a company. That person's job isn't to consult with every department about the job they're doing every week. The good HR person will lead to the right hires that make the company better down the road, it's a process.
Are you serious about the HR person comparison? You are willing to give a guy who has zero hockey experience that much power including when it comes to whether DeBoer is the right person for the job just by looking at a bunch of numbers on a sheet?
Sunny should be a consultant but not a decision maker.
