I think the disconnect between sides is that the naysayers are equating this to punishment or authoritarian rule. Like Babcock demanding to see your pics
If I was in charge I would:
Meet with Player X and all relevant departments (psych, nutrition, S&C, data, physio)
Discuss the season at a personal level. Good and bad. Acknowledge that it wasn’t where either party wants to be
Give Player X opportunity to disclose any nagging injuries. Address those immediately in the offseason
Run relevant baseline data to reference during the offseason
Set goals in conjunction with Player X that are both achievable and timely
Develop offseason training blocks and dietary guidelines
Establish accountability check ins (weekly, biweekly)
Doing this with the player gives them a level of buy in because they were a part of the process. Creating accountability check ins allows both parties to be held somewhat responsible with the end result
Honestly I would do this with the entire 40 man roster if I was GM. Players who have proven they have a strong system in place don’t necessarily need to use team resources. Players who haven’t met expectations will be given every resource necessary.
