I guess it depends on what you mean by "on the cusp." I took it to mean something similar to "on the verge," but in reality, cusp means something different. Looking it up, it says "a pointed end where two curves meet." Yes, the 76ers have been going down for a while, and will soon turn things around, so by technical definition, yes, I believe they are on the cusp. That doesn't mean much, though, as they have nowhere but up to go. They could steadily improve over the next five years, and still not be competitive enough to earn a playoff spot if they were in the West.
The 76ers are utilizing a method that works (ex: Thunder, Clippers). If they do it right, they'll be a great team eventually; I'm just not sure they're doing it right. Even if we assume Russell is the next Harden, Noel and Embiid aren't KD and RW. At some point, the 76ers need to start stringing good picks together, and they haven't thus far. Eventually rookie contracts run out, and by the time guys like Noel develop into good players, they'll be getting paid, so that advantage is gone. I'll quot what I said in the previous thread to save me some time:
Embiid has Oden 2.0 written all over him. Noel is a quality bench player. Wroten is just a bench player. Saric could be in nice...in 2017.
40M in cap space would be nice for just about anybody other than Philly. They don't have much use for it, as that won't lure anybody. Maybe they can get Rondo for a max deal. Maybe. No chance at guys like Gasol, Aldridge, Love, or even Dragic.
Their picks this year and next year look nice, but given their success thus far, I bet it's a bit misleading. They might be good eventually, but I don't see them becoming a factor in the league much before 2020.
The 76ers current roster is unimpressive to me even if you add Russell. Russell, Noel, and Embiid aren't ever going to be the core of a championship team, and certainly not anytime soon.
Assuming bad luck for the Heat and Lakers, the 76ers may have three picks so high next year that even they couldn't screw it up, and if Russell turns out to be a star, that bodes well for them. Perhaps the Heat keep everybody, the Lakers sign a big FA, and Russell turns out to be just another good non-superstar, though.
I'd agree that the 76ers are on the cusp, but not on the verge. Nothing about their current roster impresses me. They have some potentially attractive assets, though, and could make something of them. I'd guess they aren't much of a factor in the NBA until closer to 2020.
