The idea that a team could or should be dismantled to qualify for a high pick to lead it toward championships is absurd.
Nobody's arguing that. Or at least the tiniest of minorities are arguing that. There's nuance involved here. Believing that its in the teams best interest to move Green, Rondo, or whoever now in a trade brining back valuable assets and advocating wholesale dismantling just to get a little worse are different things. By stating your position like that, you're just giving us a strawman for you to call absurd.
The Cavs drafted #1, got the Flopping Crybaby for the prize and were still awful before just being mediocre because the rest of the roster couldn't play up to the requisite level.
Were still awful? From LeBron's rookie year to the time he left Cleveland, CLE had the 6th best record in the NBA, with 349 wins. That made them better than 3/4 of the league in that time. If you just look at the Cavs from the time LeBron came into his own as a player (say 05/06-2010), Cleveland had the 3rd best total record in the NBA.
This all with a supporting cast that while tailored to LeBron's skillset, was probably among the lowest in overall talent within the entire NBA. CLE, while they didn't get to keep him, did pretty well by LeBron.
Parenthetically, the Cavs other #1 picks since then haven't brought much either.
Kyrie Irving has been pretty good, an All-Star at age 21, rookie of the year, NBD.
Anthony Bennett looks like a whiff.
Teams generally win championships, not single players, as we all know, and I believe that DA wants to retain a solid core upon which to build. If the Celtics finish as the last team into the playoffs, they'll still have a relatively high pick (single number - 9) that can be packaged with other picks and a player/players to trade up. That scenario will not likely play out, but there may be a GM willing to stock up with sterling silver players rather than go for a gold(en boy) in the hope that his best players and the picks/players received in return can get them over the top.
There are a few points here.
The first one, if the difference is still so thin that team A, a half game ahead of team B, gets to get spanked by Indiana or Miami in the first round while team B gets the 9th overall pick, it might behoove us to no have a high chance of being team A. Team A (the one that squeaks in the playoffs) gets to be embarrassed on a national stage and then get a pick in the lottery that typically yields a role player. Team B gets the chance to get a higher caliber prospect by a considerable margin, AND they get at least their foot in the door of the lottery, so they also have a chance of winning the whole thing.
Trading up from 9th, or anywhere really, and into the top 7 or higher also seems like it has a very poor probability of happening. Not that it couldn't..but really, someone is gonna whiff on a pick in the top-8 for some reason. If we're picking 9th, you're better off just weathering the top 8 picks and taking BPA, because with the trove of picks we still have remaining, there is little to no payoff in the long-run for over-paying (which I'm implying would be a necessity to move up) to move up 3-4 spots when the prize at the 9th pick could be Noah Vonleh, Willie Caulie-Stien, or Dario Saric. Yeah, they're not Parker/WIggins/Randle, but neither is Aaron Gordon or Dante Exum.
