You didn't include the key factors needed in answering that question -- WE, playing time, and whether the guy is maxed out in said category.
If you had a guy with solid we playing 15-20 mpg, you can often get away with basically no minutes. If they're maxed out this is especially true.
If you had a guy with low we and/or who's sitting on your bench, you need more minutes. It's a sliding scale, a bit like setting SH minutes.
