I am going to try and see if I can give a few illustrations to highlight, hopefully, a bit better, the point I am trying to make.
I will say there are a lot of great posts, even as general as I left this topic, which shows the quality of the posters on the HSBBW.
Many of us have posted about Oregon St. I, for one, post a lot about how I love their speed/pressure game. But, if I recall correctly, I first saw that when that team showed up in Sunken Diamond in 2005. They were electric. In 2003, they were none of those things. So, did the coach change his style or did the players he recruited change it for him? Does it matter? I guess it does if you were a guy recruited under the 2003 system and you get run right off the team.
A more subtle example is the son of a friend in minor league ball. I would say the young man is talented but certainly will never be the first or second guy you notice when watching a game. You might say he is solid.
Turns out the kid is a real grinder. Gets to the field early and takes extra BP/infield and is always in the cages late when everyone has gone home. Along the way, he has always had coaches who got there early and stay as late as he needs.
Gets a new assignment where the manager has been in baseball for years and been very successful. New manager does not get there anywhere near as early and does not stay late. If you are a grinder, you grind on your time, not his. End result, team still wins, the player who has been successful gets less reps and struggles with the bat and on the field. Player gets moved, new coaches are there early and stay late, player grinds and quality improves with the bat and with the glove.
In college, a player and his family may have some choices. I thought this topic and the illustrations might be of help. In minor league ball, you don't have choices. You learn what you need to get better, and you learn how to do that in every environment...or you fail, get released or get traded. Luckily, our friend ended up with a terrific manager and group of coaches who truly helped him learn how his grinding and extra work was a necessary part of his success. Also gave him guidance on how to get it done, when it didn't come directly through the coaching staff.
