Bell tweeted out an "overdue" apology Monday to fantasy owners that selected him in their respective leagues.
"This is long overdue, but I want to take a moment to apologize to all the fantasy owners who picked me last year," Bell wrote. "I'm sorry I couldn't pull through for y'all ... but trust me, this year's about to be way different. I'm bring the [championship trophy] this year."
Bell was ranked as a first-round talent by many fantasy experts last year, but he sat out the entire season due to failed contract negotiations with the Steelers.
After parting ways with Pittsburgh, the three-time Pro Bowl choice signed with the Jets as a free agent this off-season.
The Steelers selected Bell in the second round of the 2013 NFL Draft out of Michigan State. In 62 career games across five seasons with Pittsburgh, he had 5,336 rushing yards and 35 touchdowns. He added 312 receptions for 2,660 yards and seven touchdowns through the air.
Bell led the league with 406 touches in 2017, his final season playing for the Steelers. ESPN ranked him as the No. 12 fantasy running back in points-per-reception leagues, while CBS Sports listed the tailback as high as No. 15 among all players.
