Rebuilding (partially or full) isn't pointless. The "process" the 76ers took to rebuild was basically a waste of time though. The only two pieces going forward they have is a 7fter they drafted two years ago who hasn't seen the court and whose health status is unknown and a 22yo Euro product whose value in the league is unknown. That is not a stable foundation going forward after you've been tanking for the last three seasons.
I got mixed feelings about this...
before the tanking the sixers had absolutely no legit pieces in there, Iggy left them, and jrue holiday was average. They needed high picks badly because no serious free agent was going to play there, basically sixers had no chance of landing a top free agent. The high draft picks give you realistic chance of building some, the biggest issue out of all this is that they gave these young players a loser culture, which might be a big issue later on.
So its kind of the idea was legit
Most of these eastern teams including hawks or raptors have a low ceiling. A lot of team owners build average to good teams that fill up the seats in the arena, take them to like 2nd round and thats how far they go, they dont risk at tanking nor paying huge salary in hopes of building a championship team. They basically settle for less without the big risk. And they have no realistic chances of winning championship.
Sixers however got unlucky with Embiid, yet he was still worth taking the risk, look at players drafted outside of top 3, most of them are going to have role player careers. Randle looks one dimensional, he may have a decent career, Smart is basically tony allen unless he learns how to shoot, Gordon is too raw right now, stauskas is soon to be jimmer v2, who else was drafted, exum? Horrible injury and way too raw player.
MCW draft was a mistake, he is too slow for pg position and he cant shoot, he is useless and he would never be a starting player for a contender. Also sixers tanking timing was bad because for the 3 straight years some of the best talents were tall players in that C/PF position. Sixers were simply drafting the best available talent.
