Rondo to the Lakers for Nash and Blake(expiring) and Lakers pick(5-10 range)
or
Rondo for Drummond
or
Rondo for Monroe going to a 3rd team and expiring and high draft pick or prospect from 3rd team coming back to the C's
other than getting a Lebron or Durant, those are the only types of deals I would do for Rondo.
The Lakers deal would have to be done on draft night with them making the pick or we'd have to give them a 2014 or 2015 in the deal to abide by the Stepien Rule since they've already dealt their 2015.
So do it on draft night, you would know exactly what the pick is. Also, you wouldn't have to take back Nash's contract. The Lakers have so many expirings, they'll be far enough under the cap to take on Rondo without sending back salary.
If it's the 5th or 6th pick and Rondo rejects an offseason extension offer and we don't have to take on Nash's contract for 9.7M (even though it's only for one year, I would make the deal. This should give us enough cap space, we could perhaps sign Lowry to fill the point.
