"At the end of the day, I want to have my legacy in Pittsburgh and retire there," the 24-year-old says. "I don't want to leave."
Smith-Schuster's rookie contract is expiring this offseason ... and he's expected to test the open market, even if the Steelers make him a preliminary offer.
The wideout could command HUGE dollars from teams like the Jets, Patriots or Dolphins ... but he made it clear to us while shopping out in L.A. this week he's hoping the Steelers come close to matching a big deal from other teams.
In fact, when we asked if he could see himself in a Chargers or Rams jersey in 2021 ... JuJu told us straight up, "Not right now. Until I actually get let go, other than that, I'm Pittsburgh for life."
