Blount, who signed a two-year contract with the Steelers almost a year ago, violated one of the basic codes among teammates when he left the sidelines before a 27-24 win over the
Tennessee Titans last November.
Blount, unhappy about his diminishing role in the offense, went to the Steelers' locker room before they had beaten Tennessee after he did not receive a carry against the Titans.
Never mind that
Le'Veon Bell rushed for a career-high 204 yards against the Titans and that Bell was Blount's best friend on the team.
The Steelers wasted little time in waiving the discontented Blount and the Patriots re-signed the fifth-year veteran in late November.
Blount emerged as the Patriots' best back late in the season -- just as he did in 2013 -- and is one victory away from winning a Super Bowl title.
Despite the success of Blount -- and the Steelers' need for a quality backup after Bell hyperextended his right knee in the regular-season finale -- Rooney has no regrets with how Pittsburgh handled the Blount situation.
"Obviously we don't want to have those kind things happen in the middle of the season but it is what it is and I think we made the decision (to release Bell) for the right reasons," Rooney said. "Not going to worry about it too much. We just have to make sure that we make a better decision this year and fill that position with someone we're comfortable with and who will be a good fit."
