Well, like they say, for whatever reason, the NFL won't recognize sacks before 1982, even though it was a stat and teams had been documenting them for years.
From now, and probably for good, AD99 has the official distinction of being the Rams all time leader. He'll probably be way up on the all time list, period, by the time he retires. It's just too bad Deacon and Merlin never had a chance to see him play.
"Unofficially", with the Rams;
Deacon 159.5
Youngblood 151.5 (Why it took so long to get him into the Hall of Fame, I'll never know)
Merlin 91.0
some others
Larry Brooks 74.5
Fred Dryer 74.0
Lamar Lundy 60.5
