"Usually once you start to regress, it happens faster and faster" This is an opinion, not a supportable fact really beyond anecdotal evidence, especially considering some of the players you are likely referring to are Santana, Arcia, etc who are young kids still learning how to play the game. If you are talking about Pina, sure. Talent eventually declines with age. But if you are worried about young players who show promise, none of us can predict how they will play moving forward. My assumption, based off your first two posts in this thread, is that you are worried about Santana, Arcia, etc and whether they can contribute to the Brewers moving forward. That opinion is warranted based on this season. Another fan might consider them obvious assets based on potential and learning curve and be fully expectant they will be big pieces next year and beyond. Also a valid opinion based on prior evidence. This isn't a baseball question you are asking, it is an outlook on life question.
