This would be the best case scenario:
1. The youngsters improve and the C's make good run in the playoffs (either making the 2nd round or just winning 2-3 games in the first round against a quality opponent) wherein Marcus Smart establishes himself as a PG players want to play with.
2. Brooklyn is awful and we wind up with a top 3 draft choice, which lands us a star.
3. Over the course of the season, an established player starts looking for an out, either through a trade or FA and sees that this young team, about to add a young star, as a good place to come and complete a sort-of-big-3 with Smart and this draft pick.
Then we make a run at the Finals in 2017. Best case scenario.
