If you're gearing up for your Fantasy football best ball drafts, piling together research, or scouring the internet for the most up-to-date best ball Fantasy rankings, you need to hear what Fantasy analyst Jen Ryan has to say.

Ryan is a contributor at FootballDiehards.com and on SiriusXMFantasy's "Football Diehards" show. She's also been an FSWA finalist for "Best Football Series," so if there's anybody who can help you win your best ball league, it's her.

Now she's studied the latest offseason signings, trades and cuts and has revealed her 2019 NFL best ball rankings. They're a must see for any best ball player.

One thing we can tell you: Ryan likes Steelers running back James Conner to follow up last year's breakout campaign with another strong season in 2019. In fact, she has Conner ranked as a top-10 player in her Fantasy football best ball rankings. Conner finished last season with 973 rushing yards, 497 receiving yards and 13 touchdowns in 13 games, and he'll enter the 2019 season as the undisputed No. 1 back in Pittsburgh.

She's also revealed a surprising running back who's scored just six touchdowns in the last two seasons to finish as a top-20 player. Drafting this player could be the difference between winning your league or going home with nothing.
