I will agree with that.
But the *best* argument that some one ought be in is that he had done more than someone who is already in.
Likewise, the *best* argument not to induct is to list player(s) that did more and aren't in.
statistical accomplishment (40+ ints, 20+ sacks)...the other ones did not do that. He holds the NFL record for most QB sacks for a DB and most starts. He has more forced fumbles than either the other two. He has more interception return yards than Lott even though he has less INT's.
Barber made the all 2000's team. We will have to see if he makes the all 2010's after the 2020 season.
Let us not forget the 49ers in the 80's had a pretty damn good defense too...maybe not the Ravens at its peak, but Lott did not have to carry the load by himself.
He deserves to be in the HoF along side Lott and Sanders.
