that's not entirely accurate. Nets didn't waive Darrell Arthur; they traded him for Jared Dudley and a 2nd round pick from the Suns
meaning their 'haul' for taking on those contracts was Jared Dudley, a first round pick, and 2 second round picks. Nothing too substantial but certainly an indication that the Blazers would have to give up considerably more that just a 1st to dump Turner. It's also the case that the trade happened more than a week into the off-season, an off-season when there wasn't much in the way of either cap-space or free agents....

...meaning that in this coming off-season, arranging a salary dump trade might take significant time in which teams determine whether or not their cap-space could fetch more than just an unattractive pick package for taking on bad salary. I'm not sure that delay on top of uncertainty will work in Portland's favor this summer.
I'd also wonder, looking at what Portland "needs" to accomplish, if the full-MLE is that much better than the tax-MLE (5.5M vs 9M) that the Blazers need to mortgage even more future picks to gain that extra 3.5M. Sure, if JA insists on minimal tax that might have an impact. I'd also wonder if paying 8-9M a year for either Curry or Kanter is wise. I wouldn't pay it for Curry and maybe not for Kanter.
still seems to me like the best option might be offering Meyers and the 25th pick to Atlanta before or during the draft. It would give the Blazers the breathing room for a full-MLE, but sure leave Portland crazy thin at C and PF
