If the Colts win Sunday, they will be the 12th team (and the Saints could be the 13th) to start a season 10-0 since the NFL-AFL merger in 1970.
That would offer no guarantees about their potential for postseason success, however.
Only five of the 11 teams that have started 10-0 have gone on to win the Super Bowl, most recently the 1998 Denver Broncos.
Here’s a breakdown of the teams that started 10-0 from ESPN Stats & Information:
If both the Colts and Saints win, it would be just the third time in NFL history in which two teams began a season 10-0.
The 1990 Giants and 49ers each began 10-0. The Giants won Super Bowl XXV, beating the 49ers in the NFC title game to get there.
