According to Chris B. Haynes, the Utah Jazz are expected to be interested in Tobias Harris in free agency. You can watch Haynes's video mentioning that interest below.
Haynes mentions the following teams that will be interested in Harris: Utah, Detroit, San Antonio, Dallas, and New Orleans.
The question is, how much interest will these teams show? Even if the Jazz have interest, they may or may not have the cap space this summer to sign him if they’re re-negotiating Lauri Markkanen. That said, Harris has been underwhelming in his role in Philadelphia, and it’s possible he could be had for a bargain.
