As far as I have seen, Buzzermanager really underestimates the SF position and really does not want to assign this position. Instead it seems to prefer SG for the outside-focused "SFs" and PF for the inside-focused ones. So it would probably need some minor tweaks in that regard. Other than that, it seems to assign positions quite fine in my opinion. The salaries themselves can also deviate from the ones that actually are present in BB but this isn't an issue for me either. So I would suggest giving it a try.
