That wasn't my point. I never implied there was a difference in developmental time lost. (btw, some of these single A guys who might be drafted might start out in AA or be promoted tehre quickly, so the jump is just 2 or 3 levels. (AA to MLB is 2, A+ to MLB is 3 not 4.)
My point was it looks like a lot of players barely missed a step after taking 2020 off.
Did they improve while out? Highly doubtful.
Did some or many regress? Certainly.
Did the year off ruin their careers or stunt their growth so much so that they will never recover?
I'll leave that one for you to answer.
I'd like to add that 2 years off out of 3 is a lot worse than just one years off, but again, it's not like these guys will be sitting on a couch for 365 days.
There is practice.
There is spring training, including games played.
There is Fall and winter ball. (A player selected in December could play winter ball this winter, ST'ing and fall & winter ball, next year. Sure, it's not the same as playing a full season in A+ or AA ball, but it's not nothing, either.
