Indeed. For one thing, probably nearly anyone who has successfully had good ideas is a "finisher" to some extent (though to very varying extents). Isaac Newton certainly thought hard and persevered in his researches, but as soon as you're bringing him in as an example of a "finisher" as opposed to an "ideas man" you've pretty badly undermined any distinction you were building between the two.
