To hard to compare Lloyd and Harrison, Lloyd played in a more run dominant era so he had less chances at sacks. I'm not going to look up the numbers on passing attempts by opponents. Harrison is probably the best pass rushing OLB we've had, but Porter and Lloyd were better in coverage, and both very good pass rushers, I think Porter has to be in that discussion too, only 2nd player in nfl history with 50+ sacks and 10+ ints or whatever it was when he retired.
