If you are referring to the names of the leading team members i think it does play a big part, personally i have friends in crypto that prefer to invest in new crypto IEO or ICO based on the track records of the team members and even in general perception i am sure that even if a project can be successful but without a good "name" team the investment receive for their project will not be able to reach their full potential also.
True, in terms of the success of a project the good name of a team is very necessary and also very influential in the continuity of the development of a project, regardless of what methods the team will use, but if the team already has a good name in the crypto public, then the method they will use will also be well received by investors, even though the team also chooses the method that is trending at its time.
