We don't know what the Cavs considered a "lowball" package. Maybe it was David Lee, Marcus Smart and the Brooklyn 1st. Maybe the Cavs thought that was an insult of an offer and should have included Jae Crowder and several additional 1sts. Who knows. Maybe everything seems like a "lowball" offer when you gave up Andrew Wiggins to get the guy in the first place.
Lowe has gone on record that he's not sure he would trade Crowder for Love straight up when including all factors (age, contract, D, etc.). So I really doubt he would've worded it the way he did. Instead it would've been something like "the Cavs wanted a king's ranson" or something of the like. Especially when he did say in his article "even if Boston's interest has faded".
Just saying that what Celticsblog fans think is a "lowball" offer, what Zach Lowe thinks is a "lowball" offer, what the Boston Celtics think is a "lowball" offer, and what the Cavs think is a "lowball" offer are 4 very different things.
To some fans here, the Brooklyn pick (4th at the time) was already significantly more valuable than Jahlil Okafor or Jabari Parker. To 85% of fans here, Marcus Smart was significantly more valuable than the Suns pick (3rd at the time). This forum has special logic in regards to trade value.
I've heard Lowe on podcasts with Bill Simmons expressing skepticism when Bill suggests Marcus Smart could some day be as good as Tony Allen. On the flip side, I've heard podcasts with Lowe where he suggested Marcus Smart might be a key piece Boston would need to part with in addition to their best picks for DeMarcus Cousins... so who knows how he sees Smart two years into a disappointing career.
Cavs apparently had no interest in draft picks. So they might have scoffed at any and all picks we offered them. We heard rumors that they had some interest in swapping Love for Carmelo Anthony if a team (such as Boston) was able to peak New York's interest. Perhaps the Knicks had no interest in the Brooklyn pick.
Who knows who described the offer as "lowball" or what that that "lowball" offer entailed. Michael Jordan apparently thought 4 first round picks (including this year's Brooklyn pick) was a "lowball" offer for Frank Kaminsky. Maybe we offered the Cavs a package built around Bradley, Brooklyn 1st, Dallas 1st and our own 1st and they thought we were holding back.
