I gave Rosenthal a hard time when he picked against the Steelers for the second straight week.
In the end, Rosenthal was right. This time.
The Bears, with 10 points in the fourth quarter, knocked off the defending Super Bowl champions, 17-14.
Steelers kicker Jeff Reed missed two field goals on the day, including a fourth-quarter try that would have given Pittsburgh a late three-point lead.
After that miss, the Bears moved the ball into position for Robbie Gould to nail the game winner from 44 yards, with 15 seconds to play.
Stefan Logan fumbled the ensuing kick return, the Bears recovered, took a knee, and that was that.
The 1-1 Bears go to the 1-1 Seahawks next week, and the 1-1 Steelers visit the 1-1 Bengals in a key early-season AFC North contest.
After a horrendous debut with the Bears last Sunday night, including four interceptions and other bad throws that were dropped by Packers defenders, Chicago quarterback Jay Cutler completed 27 of 38 passes for 236 yards, two touchdowns, and no interceptions.
His favorite target was rookie Johnny Knox, who caught six passes for 70 yards and a touchdown.
Neither team had much of a running game. Matt Forte gained 29 yards on 13 carries for the Bears. Willie Parker led the way for the Steelers, with 47 yards on 14 tries.
