39 postseason overtime games.
From 1970-2000 there were 15. About 1 every other year. 11 of the 15 took at least 8 minutes of OT to decide. 4 of the first 7 went into double overtime and two others took more than 13 minutes of OT. Those first 7 averaged more than 15 minutes each.
From 2001-2021 there have been 24 postseason overtime games, more than 1 a year. Only 8 of them went more than 6 minutes with only 5 going 10 minutes or more. Two of those went to double OT.
The Rams were involved in the 3rd shortest OT game in the postseason (1:06 in 1989 PS) and the 6th longest (15:10 in the 2003 PS).
What makes me smile is Green Bay, with Favre and Rodgers have been in 6 postseason OT games since 2000 and have lost 5 of them. They lost in 4:48, 2:26, 1:18, 3:19 and 1:05. The only win came in that Seattle game when after winning the toss, Hassleback said, "we'll take the ball and we're gonna score". IIRC, he threw a pick and the OT lasted 4:25.
Controversy?
A facemask on Rodgers that wasn't called as Arizona returned a fumble to win 51-45 in 1:18.
