Fungo, very interesting question. I think there are variables from DI to DIII and even variables between Northern and Southern teams. Especially for the DIII teams in the North, they carry more pitchers and more see playing time. Their season starts later and when it does they usually play 6-8 days in a row in the South or West. When they return North, many will play 5-6 games per week in April/May to get a full season in and then they have playoffs where they may play 5-6 games in 3 days. Southern DIII's play more like a DI schedule with usually 1 midweek and 3 weekend games but they also have tournments. DIII also plays more 7 inning games as part of weekend doubleheaders. In the South I think most teams carry 12-14 pitchers and 7-8 get the vast majority of innings. In the North I think they carry the same number of pitchers but most of the 12-14 will see a lot of innings.
