Just going to point out that the 24 tackle game by Luke was also the same game Hardy got 3 sacks and 2 TFL.
In that game, which we won 17-13, Hardy's first sack came on third down. The sacks was for 11 yards and moved the Saints out of field goal range to the Carolina 39 where they had to punt to us. Hardy then tacked on another sacks later in the game which also ended a drive for the Saints.
During a must win game for seeding and trying to clinch a playoff spot, Greg Hardy along with Luke stepped up.
In the final week of the season we beat the Falcons by 1 point to clinch a top seed in the playoffs. Hardy had 4 sacks. The first sack came in the Panther red zone and forced a field goal instead of them going for a touchdown. Hardy's next sack came on third down again and ended a drive.
Point is, its hard to say who is more important. Both of them have grown into great football players. Luke is our smarts, Greg is our attitude. But without the other guys around them they don't shine like they currently do.
