The official twitter account did a little tribute clip on Mercury Morris today and mentioned that 39 and 22 had the first dual 1,000 backfield in NFL history in 1972. I recall there was something a little screwy about 22's yardage total. For some reason they had tallied him having 997 or 995 yards rather than 1,000 supposedly based on his not getting credit for some yards on some play. Then the NFL said they reviewed whatever it was and gave him the yards to reach exactly 1,000 yards for the regular season. Anyone remember what that was about?
