My son's experience in the ACC, 2008-2012, was very similar to those described above. On most weekdays pitchers were generally at the field from noon until 7:00 pm. Quick dinner, followed by mandatory study hall of 2 hours. (Study hall could be exempted after first semester if your grades were good enough). Saturdays and Sundays were usually another 4-5 hours, sometimes more. Mondays were supposed to be "off" but they really weren't. Even though the team did not officially "practice" there were still meetings, bullpens, and weights.
Early season mid-week games usually started at 5:00. But, as the weather warmed up they were pushed back. It was not unusual to finish a mid-week home game at 10:00 to 11:00 pm. Mid-week road games usually involved leaving at 2:00 (or earlier) and getting home around 12:00-1:00 am.
The other thing that always got me about mid-week road games was that EVERYONE traveled, even pitchers who had thrown extensive innings the previous weekend.
Weekend road trips usually involved leaving on Thursday. Sometimes as early as Thursday morning, depending on the length of the trip. Yeah, there was wi-fi on the bus. But, good luck studying on the bus if you're anything other than a jock major. Some of those road trips ended with the bus getting back around 2:00-4:00 a.m. Monday morning.
Coaches and college staff will, let's call it exaggerate/sugar-coat the facts. Son was an engineering major. During the recruiting process we asked what would happen if he had a test scheduled on a Thursday or Friday during a road series. We were told by the academic support staff that they could arrange to have the tests proctored at the school they were visiting. Unfortunately, son's engineering professors never got that memo. If son had a test scheduled on Thursday or Friday he usually had to take it earlier in the week, before the rest of his classmates.
The NCAA rules regarding allowable practice time are joke. They are totally ignored at many, if not most, schools. As others noted earlier, when you get to the college level, it's a JOB. College athletes are forced to play way too many games in much too short a time for most kids to get a real education. With basketball and football it's all about the money. But, there is no money in college baseball. With baseball it's driven by the coaches.
