They definitely shouldn't have three SGs as untouchable in trades. Even if Wesley is considered a PG only going forward, having three guards locked away is a lot. I don't think they should be throwing them away, and in a scenario where SA were a solid playoff team, they'd probably be part of it. I can't disagree strongly enough with the idea that the Spurs being such a team this year could ever be construed as a bad thing. The four-seed is going to win 50 games. If the Spurs are pushing 50 games, it's because they have at least one All-Star, not because they're scrappy. You suggested as much and I agree that they're likely going to lose some more games. While I don't think they're going to fall off to be one of the worst teams in the league, they'll be a play-in team. If Johnson and/or Vassell makes legit All-Star or MIP noise, may they'll host a play-in game. They might even win it. But I can't see them even being a six seed as is.
But could this current team make the right trade to become a non-play-in playoff team? Maybe. It'd have to be a talented player for whom it also works out. Like Fox but with Fox fitting in and not stifling the other guys. If this were next year, Maxey would be on the table. I just don't think there's a scenario where the Sixers move him outside of getting that third star. But I am a fan of trading a protected natural pick that basically locks SA's first down for years. Detroit, Sacramento, Washington and Charlotte all made deals that basically prevented them from using future firsts on minor deals for years. That has protected them from making impulse buys using their future stock. I'd like to see the Spurs do something similar if they can get the right player in the exchange. I want to say Detroit used their pick to get Isaiah Stewart, who's been very good for them. Sacramento used theirs for Hueter, whom I haven't followed. Washington used their pick to get rid of Wall's contract for Westbrook, whom they flipped for a pick themselves. None of them are on the hook to convey a good pick, but they'll be able to use the good natural picks they have without fear of making a short-sighted in-season trade.
