It seems weird to me that you could look at the back end of the playoff picture in the East, see the vulnerabilities of the teams in those spots, and think the Sixers have a huge leap to make.
Miami just doesn't have a lot of pieces to make a sustainable run. Milwaukee just lost Jabari to another ACL injury. Chicago might trade Jimmy Butler. Indiana might trade Paul George. Charlotte is a very mediocre team with no real stars apart from Kemba. Detroit does not have a star either. The Knicks lack any future pieces apart from Porzingis, and they have little cap flexibility to build around him.
The leap to the playoffs is not that out of reach. Consider the Sixers may very well end up with 30+ wins this year, is the addition of Simmons, development of Embiid, Saric, Noel, Covington, and cap flexibility + draft assets really going to make it that difficult to get to the requisite 40-42 wins range? If we were at 10 wins like last season, then I would be all for Skeeza's argument.
I get Skeeza's point that we have to wait and see what Philly does to flip the script, but Philly may be able to stay in neutral and climb to the playoffs given the state of the Eastern Conference.
