2020's widened strike zone (accepted in order to move games along more quickly) and 2021's deadened ball are compounding to make historical OPS less important as a predictor of performance, I'd imagine. The SLG guys aren't hitting as many homers, while the OBP guys aren't as valuable if they can't actually knock that runner in from 2nd or 3rd with 1-2 outs. As expected, this has greatly depressed current batting averages, in theory making AVG a more valuable attribute this year. In the short-term, GMs should pay for AVG, which is somewhat tricky given the luck/BABIP factor. But it's their job to figure it out. In the long-term, assuming the deadened ball stays, hitters need to go back to emphasising bat control over power, while hopefully the umps or robo-umps give us a narrower strike zone.
