The Detroit Pistons are stuck in a 21-game losing streak, so it's safe to say they need an influx of talent.
Every position needs an upgrade, including power forward, as the Pistons don't really have one. Isaiah Stewart is better suited to a backup big role (center or power forward) and isn't dynamic enough offensively for the modern NBA. Isaiah Livers has not been healthy much, or very good when he has been, and is on an expiring deal anyway.
Unfortunately, a quick look at the free-agent power forwards for next offseason shows that pickings are indeed slim. Here are some possible options for the Pistons ranging from stars they aren't likely to get, interesting young players and a couple of flyers. Let's start at the top.
Detroit Pistons free-agent power forward options
LeBron James
I'm sure the greatest player of all time wants to finish his career on the worst team in the NBA. The only way this is happening is if the Pistons do something wild like draft Bronny James with the #1 pick. LeBron has long said he wants to play with his son, but he'd probably start his own league before allowing the two of them to play in Detroit.
Tobias Harris
Harris is another player who is in the stage of his career where winning will be more important than money. Harris is still a solid contributor on a good team in his 13th season. He's the definition of consistency, which makes him the type of veteran player the Pistons could use. Even if the Pistons offered him the most money, it's hard to see Harris wanting to join the worst team in the league at the tail-end of his prime.
Pascal Siakam
Have talked about him a lot and on paper, he is a nice fit who would move the needle for the Pistons. But he's not had a good season, and his 3-point shooting has regressed. He'd be a good second scoring option, but giving him a max deal would be seriously risky. Not to mention the fact that there are at least three other teams already kicking the tires on a trade. No team is going to trade for him without the intention of re-signing him, so if he is traded, he's likely off the table for the Pistons which is probably a good thing.
