As you watch it, you see Haley get a sack on Ripen. I'd suggest most of those of us who were around and watching the team at that time had the idea Haley tore it up that year.
That sack you see was one of six in that season.
Going into the 92, the sting of the Detroit game from the year before made it apparent Dallas needed a better end rusher. The story goes Jerry went out and got Haley.
Haley's stats in no way reflect his contribution in 1992. As teams focused on him, the rest of the line became meat eaters. Haley brought the mojo, but also was a leader that gave the line teeth.
Being the number one defense in 92 was great. But they were a bend don't break defense. It was the team speed which allowed Dallas to eventually dominate the game late.
