The Cavs might move the #1 pick for a star veteran, because they want to win rather than get younger. They're not going to trade it for two lesser picks.
Bingo.
How about:
Rondo sends:
Rajon Rondo
Jared Sullinger OR Kelly Olynyk
2014 Pick #17
Cleveland sends:
Andersen Varejao
2014 Pick #1
Works according to trade machine:
http://espn.go.com/nba/tradeMachineCleveland can then start Rondo at PG (moving Irving to the SG spot) and trade Dion Waiters, who clearly doesn't mesh with Irving.
Rondo + Irving makes Cleveland instantly relevant.
Boston can then Draft:
* Embiid (rim protection) + Smart (replacement for Rondo) or
* Exum (replacement for Rondo) + Vonleh (rim protection) or
* Parker (volume scorer) + Vonleh (rim protector)
Not sure if Cleveland would be up for this, but I'd definately be happy to offer!
In a draft this deep, having two top 6 picks makes it pretty hard to go wrong...
