Wilson has looked better this year, Fields has a stronger history (both as recruit and last year). My logic was that Fields has proved himself in big games (see Clemson) whereas Wilson hasn't (no opportunity) so they might be more comfortable with Fields on the big NY stage.
Really it's 50/50 though. I live in Atlanta and people here are desperately hoping Jets take ZW at 2 so they can maybe get Fields at 4, so maybe that influences my thinking.
