It was still largely a running league when Lambert played. Just so you know Lambert didn't start at linebacker in college until Youngstown States' starter left to be a roadie for the Rolling Stones. Jack Ham and Andy Russell were better players imho.
#1 Lambert played at Kent State
#2 what kind of ridiculous statement is to say they didn't throw much so we diminish that . If you are the best middle linebacker in pass coverage ...they might have thrown the ball 18-22 attempts per game then but there were 27 other middle line backers during his career who were not as good against the pass as he was. He was better than the greats who played before him against the pass. Given he was above average against the run, had the attitude, the look, etc....I rank him #2 of all time.
Going by the example you state, would be like suggesting Joe Montana was not as good as Drew Brees, Manning, Favre, etc..etc. Because back then he didn't throw it as much as those guys listed.
Jack Ham was the best outside linebacker ever. This one is not really close to debate. (I'm not talking about 3-4 ) outside backers that rush every play (LT)...
I'm talking about stay at home contain make the tackle on the Ryde linebacker.
Ham was so smart first of all...secondly as was he the sure tackler..as defensive players were then who came under a prime Joe Paterno.
The Andy Russell I knew wore his heart on his sleeve. Everyone loved Andy. Andy was a very solid, good player. He wasn't on the same level as Lambert and Ham on that defense. Again not that Andy was bad, those other two were just that good.
It is a unique debate to have because of the different eras.
Butkus, Nitschke, Mike Curtis, ...all could play on my team...Spielman was a tackling machine.
As well as Doleman, Jackson, Taylor...Hendricks, the whole front Nine of the 85 Bears...
Could I also have the college only version of Hugh Green? Whoa.......
