To be honest, there are names that I cannot understand why they appear in this poll. Ron Dennis, Christian Horner, Flavio Briatore, Jean Todt to name a few. I cannot condone the actions of FB in Singapore, nor do I believe that his win at all costs mentality, which drives some people to cheat and use nefarious and underhanded means should be celebrated, however, you cannot deny the success of these people. I would add that the single minded nature and personality of some of these people can be a put off, that alone does not make them a bad team leader.
I would name Nick Fry, Tom Walkinshaw, Colin Kolles are all people who have contrived to do very little with what they had at their disposal, but Nick Fry takes the prize for me.
