That's why I said it is all relative. Einstein told me that when we went to school together (he helped me with science and I helped him in math). All these things balance out. You can more prime years from Harper and Soto, but you have to give twice as many years as Bregman and Alonso.
In the case of Lindor, here are my key inputs:
He's hit well since he returned from injury, so I see no performance issue.
He's averaged 158 GS over the past 4 years, so I see little l/t injury risk.
He's averaged a consistent 6.0 bWAR over those 4 years, so I see no near-term aging risk.
At a discounted $22M, I see him as a relative bargain compared to last years FAs.
I'm not concerned about the loss of Mayer. If we have Arias, Lindor & Durbin for the next 4+ years, Mayer would have no slot.
I'd gladly wager he'll have a higher bWAR next year than Bregman, Alonso or Schwarber.
And he is at the position that needs the highest upgrade.
