Lately there has been a narrative that UCLA QB Josh Rosen would be a better fit in New York because of his upbringing and USC QB Sam Darnold would work better in Cleveland because of the salt of the earth type of people that live here despite both going to college in Los Angeles.  Yesterday Rosen's coach from UCLA Jim Mora Jr. said the Browns should take Sam Darnold because he fits the blue collar attitude of Cleveland and that Rosen fits better in NYC and that lead Ken and Anthony to ponder why this thought exists.
