Well Chad Ford says that Flip is realizing that the C's might have the best offer:

Well, that makes me happy 
that seems like way to much to give up for Love. I mean 6, 17, Sully/Oly, plus future firsts. That is a king's ransom for a player that is not a king (and may not even be a queen).
I don't think so.
I view it as, you're trading pieces which may or may not be good for a player who is already good.
The other team (in this case, Minnesota) gets quantity while the Celts get quality (ala the KG trade.)
Yeah, but the quantity is mostly known. This isn't like the Deron Williams, Carmelo Anthony, Pau Gasol, KG, etc. trades where the draft picks are all in the future and could be anything. I mean look at what Boston gave up for Ray Allen, the 5th pick in a very weak draft, a young PG in West, a future 2nd, and the old broken down contract of Wally. Boston also picked up an early 2nd rounder that year (which was Glen Davis). Now don't get me wrong Ray Allen was much older than Kevin Love and Love should get more in return, but not a king's ransom which is exactly what 6, 17, future firsts, and Sully/Oly is.
