Does recent NBA history tell us Cavs will sustain their big leap?

Will Cavs sustain their big leap? What happened to the other teams

The Boston Celtics were the team most unlike the Cleveland Cavaliers in this group, putting together a trio of aging stars to try and win a title. It worked, and the Celtics made it to the NBA Finals twice and were a perennial contender for years before they started to break down and Boston moved its stars for draft picks.

The San Antonio Spurs were probably the most similar, adding a rookie in the draft who looks like a future superstar. Tim Duncan was an All-Star in his first year, which Evan Mobley was not, but he was also three years older than Mobley. The Spurs not only sustained their success, but they built one of the all-time dynasties in sports history, winning five titles over the next 17 seasons.

Finally, the Phoenix Suns also had a long-term foundation to build on with Steve Nash, who won two MVPs while running and gunning in the desert. While both the Sputs and Celtics won at least one title, the Suns never broke through, but they won at least 50 games in five of the next six seasons.
