NEW ORLEANS — A big comeback. A blown call. And, finally, a booming kick that sent the Los Angeles Rams to the Super Bowl. After rallying from an early 13-0 deficit, the Rams stunned the New Orleans Saints with Greg Zuerlein’s 57-yard field goal in overtime for a 26-23 victory in the NFC championship game Sunday — an outcome that might not have been possible without an egregious mistake by the officials in the closing minutes of regulation. Los Angeles cornerback Nickell Robey-Coleman committed a blatant interference penalty with a helmet-to-helmet hit inside the 5, forcing the Saints to settle for Wil Lutz’s 31-yard field goal that made it 23-20 with 1:45 left in regulation. That was enough time for Jared Goff to lead the Rams down the field for Zuerlein’s tying field goal, a 48-yarder with 15 seconds remaining. New Orleans won the coin toss and got the ball first in the extra period.
