"This is the most resilient team that I've ever been around," coach Chuck Pagano said. "They've got more grit than anybody, any team I've been around."
Both teams scored off a blocked kick. The Seahawks (4-1) ran for 218 yards, averaged 6.4 yards per carry, had better field position and ran more than three dozen plays in Colts territory as they played keep away through the first three quarters.
None of it mattered to Luck. He still found a way to win. On the decisive drive, he took advantage of a pass interference call against Richard Sherman, got another break when Pagano won a challenge on a third-down spot that turned fourth down into a first down.
After consuming nearly seven minutes, he gave the ball to Brown, who squirted through the middle for the go-ahead score.
Luck finished 16-for-29 for 229 yards with two touchdowns and picked up his ninth fourth-quarter comeback win in 21 career games.
"A win is a win, if it was ugly, if it was great," Luck said. "To come back, you hold on for dear life, but a chance to beat a good team in front of our home fans, to get back on track at home, we take a lot of pride in that."
Seattle dominated the first half, seemed to be in control most of the game, and Wilson went 15 of 31 for 210 yards with two TDs before throwing an interception on the Seahawks' final play. He also ran 13 times for 102 yards.
Lynch ran 17 times for 102 yards, and the defense limited Indy to just 317 yards of offense, 120 of that coming in the fourth quarter.
