I have the first overall pick this year in a fantasy football dynasty league. I NEED a good RB. For those who don't know what a dynasty league is, you keep every player you draft forever, unless you trade or release them. And you only draft rookies each year. So my plan is to draft one of these two RBs with the number one overall pick this year. Need some opinions! The scoring is PPR. Fournette or McCaffrey??
