I have heard of two college players at 2 different schools walking away (quitting the team) less than a month before the season starts. These were not cuts. In fact, one probably would have been a starting OF.
How often does this happen? And, typically, do colleges replace the players and how? (In one of these cases, I know the school "brought back" a player who was cut at the end of the fall but who remained at the school.)
