I'm not sure if this is the best place to post this (there are several Pistons threads right now), but one of the big Pistons mistakes was blowing the 2020 draft.
It seems like they went all in on that draft and missed on some really good players.
Pick #7 - drafted Killian Hayes
Pick #16 - drafted Isaiah Stewart (traded Christian Wood to get this pick)
Pick #19 - drafted Saddiq Bey (traded Bruce Brown, Luke Kennard amongst other things)
Can't trade so many solid veterans and then miss on these picks. Stewart seems to be a solid role player and they used Bey to get James Wiseman (also part of the 2020 draft), but Hayes is terrible and this is his 4th year and he looks like a rookie out there.
They missed on Haliburton, Vassell, Tyrese Maxey, Quickley, Desmond Bane.
