The C's best assets are:
Rondo - All-Star PG.
Celtics own picks - The next 2-3 years could be lottery picks.
Nets picks- 2014 pick will be in the 20's, 2016 is the best Nets pick because they could be a lottery team and is unprotected plus 2018 pick.
Clippers pick- 2015 mid 20's pick.
Bradley- great defensive asset could net a pick in the trade deadline.
Bass - Solid role player on a decent contract could net a expiring contract and 2nd round pick.
Sully- Young PF could be a solid starter
KO- Same as Sully
Fav - Backup Big on a cheap contract
Courtney Lee- Good role player but overpaid.
Hump - Huge expiring that could facilitate a trade.
Green - If he averages 15-17 ppg could be a good trade asset.
