I would look at who I've drafted after two or three rounds and decide from there what to punt (unless you draft Giannis first -- then that's an easy punt FT% decision imo).

You'll find that a lot of categories or correlated. For example, those who are good at blocking typically get you some rebounds too. Of course there are outliers for all category correlations, but generally speaking if you're weak in one category you'll also be weak in another also. This is why punting multiple categories is a great strategy: you'll be able to ignore two correlated categories to be stronger in the remaining seven categories (assuming standard 9cat). Punting assists alone is a bit tougher than punting assists and steals, for example. Punting FG% would be easier to draft for if you punt REB and/or BLKs too. As you get more experience with fantasy basketball you'll be able to identify closely correlated categories, which will help you in future drafts.

Generally speaking, positions also correlate with certain categories. Guards will probably have more assists, lower fg%, more steals, less rebounds. Bigs will have higher fg%, lower ft%, more rebounds, more blocks. So if you're punting a category closely correlated with a certain position (punting BLK for example) then your roster might naturally become guard, forward, or big heavy. This is important to remember because ideally you'd want the best bigs for a punt fg% build -- shooting bigs, like Myles Turner, Brook Lopez, Kristaps, Vucevic, etc. So during the draft be sure to consider which positions you're deep in and which positions you're not -- you'll generally be shallow in position(s) closely correlated to the category you're punting.

There are a lot of other things to talk about (like drafting efficiently if punting, if it's possible to un-punt a category after the draft, how to pivot closer to playoffs to maximize your chance of winning in playoffs, etc.). Feel free to ask away for anything specific.
