Personally, I prefer to front load the study hall minutes into the freshman season. I don't know that the gpa helps anything, but I do like not having to worry about giving any SH minutes to players that are actually seeing court time. For internationals, I generally start with 10, unless the scouting told me they were dumb, then I go with a little more. Basically, my approach is to try to get them to 3.5 their first year, then everything is golden.
