The odds of getting a superstar through trade or free agency is, in my estimation, just as unlikely as doing so through the draft, especially if you aren't a glamorous location or in a tax-free state. At least through the draft you have the player for a longer period of time and see him develop throughout the years.
If the Sixers wanted a competitive team they could easily have one tomorrow. They have the assets to flip the switch because it's really, really easy to go from a bad team to a mediocre one. The hard part is going from a mediocre/above average team to a very good/contender level team, because that requires superstars and there's just not enough of them for all 30 teams.
Okafor, Saric, Noel, Covington, their draft picks, and even Embiid could all fetch veteran talent easily. If they wanted to field a starting lineup of Ty Lawson, OJ Mayo, Gallinari, Taj Gibson/Markief Morris, and Roy Hibbert they could do so tomorrow.
Young players with potential and superstars are the most valuable commodities in the NBA. Why? Because they're both underpaid. Everybody else is grossly overpaid by comparison and due to the salary cap the more underpaid guys you have, the more talent you can actually squeeze onto your team.
Put it this way: The Cavs are paying LeBron James 23 million dollars this year. The Sixers could easily sign two OK players 11.5 million a year, say an OK starting center and shooting guard. However, the production they are getting from those two players for the same money is nowhere near the impact LeBron, or any other superstar for that matter is providing. The problem is those stars are not available to the Sixers. So instead of paying average/above average players that money they're trying to get that superstar through the draft. Is that so hard to fathom?
Like Zach Lowe says frequently, tanking is no guarantee, it's just the best option out of a lot of unlikely options.
They're all unlikely options, naturally. Though, trading for stars happens more than people like to believe. In the past ten years, a whole list of "stars" have been traded (Kevin Love, Carmelo Anthony, Dwight Howard, Chris Paul, James Harden, KG, Ray Allen, etc) But the best part of our rebuild so far is that Ainge has us perfectly set-up to pursue all avenues in chase of that superstar.
The Sixers are the perfect counter-argument to tanking. Sure they could trade their pieces and make a competitive team, but why tank for 3 years in a row just to get a 40 win team out of it? It's of course possible to get a franchise changing star in the draft (LeBron, Davis, Durant) but it's unlikely all the same, and if you go to the lengths the Sixers have to get one that way, your create a culture of losing no one wants to be a part of. Are any "top-tier" FA's going to consider Philly? Not a chance. Will Cousins, for example, sign off on a trade to Philly? No way. Full tanking kind of forces you to play one hand, and Ainge has done a masterful job keeping us out of that mess.
Were one of the youngest teams in the NBA, with a roster full of high-effort young guys with potential, and were good enough right now to make at least a respectable playoff run, which keeps the door of FA wide open. Guys will consider coming here thanks to Stevens, the great FO and the roster we currently have.
Better yet, thanks to the Brooklyn trade, we have a 45-50 win caliber playoff team full of guys 28 and under while STILL being able to get a top 5 pick. On top of having 2 more picks (likely at least in the lottery, if not top-10) coming from them the next two years. It's difficult to tank hard enough to get a top-5 pick. You have to make yourself pretty bad, which would be kind of difficult with our currently deep roster. But why would we? Brooklyn is literally tanking for us. We have a legit shot at the #1 pick this year and we didn't even have to suck to do it. It's an extremely enviable position to be in, and gives a great hand to play at the draft table while, unlike Philly, we still remain credibility in the eyes of the players.
Because of the picks and the roster, we have a plethora of trade chips to play with, and that pile of assets looks better and better as we get closer to the conveyance of the Brooklyn picks. Just about every player thrown in the rumor mill this year is going to get connected with us because guys around the league know we have both the assets to make some of the best offers and a team guys will want to play on. Just last year, we thought we were light years away from contention, but now that doesn't seem to be the case. If you put a star like Paul George on this team and you've got a team that could likely challenge the Cavs.
Were about as well set up as you could possibly ask for since we started this rebuild. We have great hands to play at the draft, in FA, and on the trade market, plus a young team on the rise and an already established culture of hard work and defense. Tanking would destroy all of that, put all our eggs in the draft basket, likely alienate/lose Stevens (who's one of our greatest assets, IMO) and for what? A 20% chance at Ben Simmons instead of a 14% chance? No thank you. We need to just stay patient. I think you'd be hard pressed to find a team better set up, on the whole (including culture, coaching, management, ownership, cap space, current roster, draft assets, etc.) to succeed better than we are right now.
