Question

What are the only two teams that have been led in touchdown catches by different players in each of the last seven years? One team comes from each conference. One team was coached at the time of the AFL-NFL merger by a man who later (in his second head-coaching job) lost a Super Bowl against the other of these two franchises.

Answer

The Rams (with Donnie Avery, Brandon Gibson, Jared Cook, Lance Kendricks, Tavon Austin and one season shared by Danny Amendola and Michael Hoomanawanui).
And the Dolphins (with Brian Hartline, Davone Bess, Brandon Marshall, Anthony Fasano, Charles Clay, Mike Wallace and in the most recent year a share between Jarvis Landry and Rishard Matthews).
The head coach in the hint was George Allen, who with his Over The Hill Gang lost a Super Bowl against the undefeated Dolphins.
