I'm a couple seasons in and just got the newest Draft Pool. Majority of the pool are HS guys, and that's also counting 20 and 21yr olds as well.
On the settings, it's pretty standard, 40% high school target, I didn't change any of the settings. Only thing recent is I recently added a Short Season A league in the latest offseason, which seemed to increase the # of rounds to 32
I can put together the .dat file if that is helpful...
