How rare is it for a quarterback to throw a touchdown pass to a player, and then throw a touchdown pass 12 years later to the same player on a new team? Well, it’s never happened before. The closest was with Randall Cunningham and Cris Carter; the duo connected for a touchdown pass in November 1987 with the Eagles, and last connected for a touchdown pass in September 1999 with the Vikings, a span of nearly 12 years.
The table below shows, through 2017, all QB/Receiver pairings where the duo connected for touchdown passes on different teams. I have used “different teams” liberally here (e.g., including the old Browns and Ravens as different teams), but you can consider them the same team if you like.
Stabler and Casper hold the record for combined touchdowns on two teams, at 45, although most of those were in Oakland. Bledsoe/Glenn, Cunningham/Carter, Cutler/Marshall, and — if you want to include them, Testaverde/Jackson and Testaverde/Alexander — are the only pairs to connect for double digit touchdowns on two different teams.
