With respect to the comments about no star players being willing to sign with the Cavs, that is probably the case. I see the Cavs building a team similar to those near-miss teams of the 90's that had good players at every position but no stars. Obviously I'm referring to the Price, Harper, Ehlo, Nance, Williams, Daugherty team. A lot of talent, but no Michael Jordan. They were only able to go so far.
I see the Cavs building a team similar to the Trail Blazers, who had 26 winning seasons in the last 34 years and 13 seasons with 50 wins or more. Yet they only made the Finals twice and lost both times (in 1990 and 1992). Looking at their win share leaders over the last 33 years, their best players were Drexler, Terry Porter, and Lillard. Drexler is a Hall of Fame and a 10-time All-Star; Lillard is a five-time All-Star at age 30. Their two Finals appearances were when they had Clyde.
The Blazers team of recent years fits the current Cavs profile with a high scoring guard tandem of Lillard and McCollum, a 16 and 10 guy at center (Nurcic), a 6'8" power forward averaging 9.4 and 7.5 (Aminu). In 2018-19 they won 53 games in the tough Western Conference with that lineup, plus Harkless and Layman at small forward, each averaging 7.6 ppg. Once the Cavs get their starting lineup of Dre, Love, Okoro, Sexton, and Garland healthy they could have a similar team.
The difference is their second team of Allen, Nance, Cedi/Windler, Porter, and Delly would be a lot better than what the Blazers had to work with.
But the Blazers never had a LeBron, Steph Curry, Anthony Davis, Kawhi Leonard, or Jimmy Butler type to elevate their team to a Championship and it's fair to wonder if the Cavs will become another Trail Blazers in a best case scenario.
By the way, the Indians are doing the same thing. Seven winning seasons in a row but no Championships. Always the bridesmaid or in the wedding, but never at the altar. But at least the Cavs are in a sport with a salary cap. It will be interesting to watch the Cavs play the Nets next season when the Cavs can throw waves of talent up against a team with three superstars and little else. Kind of like the 90's Cavs against the Bulls with Jordan, Pippan, and some role players.
