I get that but that is also not all they have to do. As TPM, said somewhere up here they have to scout 2-3 teams a week with 11-15 batters and make scouting reports for their players which takes a lot of time. They also have to prepare a pitching plan for 4-5 games a week for starters and bullpen. There is only so much time in a day.
We talk about turnover and new players coming in. A PC has to figure out who can pitch and who just throws. Try to fix a few things in a pitcher but that is about all they can do. The average D1 team now has 20-25 pitchers. Now we know that only about 10-12 of those are going to be used. So do you invest your time in the 10-12 that are going to help you win or the 10-12 that are not going to help you win this year and may not be here next year. It is tough. You only have 20 hours a week that you can work with players. The math does not work out. I know it may not be fair but coaches have to make choices and everyone of them and us would do the same. Invest in the ones that are going to help you win. You also understand that most PC's do not have qualified volunteer coaches who can help them work with pitchers so it is hands on.
