No, a mere 8 people did not bring Lehman Brothers down. It was a group effort to destroy the 150 year old firm. And all it took was excessive risk, massive exposure to mortgages, enormous leverage, insufficient capital.
This guy is so wrapped up in his old firm — he has no ability to see what is actually happened.
Its sad and I feel bad for the folks who worked at LEH — but this 8 guys nonsense is a crock.
