There is a difference between a throw-in and a quality secondary piece. Just because a player is a quality secondary piece in a trade does not mean he is a salary throw-in or not valued by either side.
I would say that when we traded for Green and Plumlee, we valued both pieces similarly. When we traded for Barkley, we weren't necessarily "giving up" on Tim Perry and Andrew Lang, even though Horny was the main piece. If Len is included in a trade, even if he is not the main piece, it will not be because we are giving up on him. It will be because we value what we are getting back more.
When we traded Robin Lopez, THAT was giving up, same with Armon Gilliam and Kendall Marshall.
Sure there is but I don't see it in the trade offer we're talking about. His suggestion was "Lavine, Dieng, protection off the T-Wolves pick that we own for Bledsoe and last year's #5 pick Len". There is no way that package represents anywhere close to fair value for a near max player and the number 5 pick from the year before.
Look at the pieces we'd be receiving. The draft pick protection doesn't mean much since giving them Bledsoe probably moves their pick out of premium range anyway.
Dieng has potential and it's a position of need but he's still a fairly undeveloped project. Plus he missed 22 games last season. He wasn't out 22 straight games either, it was a night here and a night there (he was out for games 1, 3, 6, 10, 12, 13, 16, 17, 22, 23, 24, 26, 28, 31, 33, 35, 38, 39, 42, 47, 58 and 72). That's alarming although I'll admit I don't really know the reasons for those absences.
And lastly, Lavine is a long shot to ever start for a decent team. For Bledsoe alone, that's a one-sided deal IMO. Adding Len to that deal screams "throw-in" to me (on our part). If we still thought he was legitimately the big man that some thought should have gone first in last year's draft, there's no way we'd include him in a deal like this.
