Ugh, of course there are estimates used. Literally everything we do is estimates. But the way you speak of estimates, I assumed that you meant ungrounded estimates - if you have a problem with mathematical estimates, then I have a hard time imagining you do indeed use math as much as you say.
Ah, I see, you've completely ignored everything I said. Now I get it.The kind that say All-Star and Team USA DeMar DeRozan is the 17th best SG in the league and that Waiters and Olapido are much better. I'd say that's ignorant of nuances of the game, and totally dependent on complex formulas based on a shit load of estimates and assumptions applied to some imaginary team play.
If you want to keep presenting those rankings as an evaluation of WARP you are either unable to understand English or being deliberately disingenuous. I've stated, several times, that those rankings are NOT based on WARP, which is a fairly straightforward aggregation stat (probably the lesser of it, WP and WS, but still solid), but based on projections - projections which differ radically from what the past year's WARP tells us about these players. WARP tells us that DD was dramatically better than both Waiters and Oladipo. So why do you use Waiters vs DD vs Oladipo as an argument against WARP?
