Meb does not have the most wins or the fastest times in American history, but with a Silver medal, a NYC win, and a Boston win: Is he the most accomplished American marathoner of all time? Those Americans from the 1970s and whatever (Shorter, Rodgers, etc) never had the East African pool of competition to deal with. I would have to say there's at least a reasonable argument to be made to say Meb is the American GOAT.
