What if Julio tears an ACL? What if Matt Ryan is revealed to be a Russian spy? What if Rex Ryan is hired to be the Falcons' offensive coordinator?
Cook in Cleveland would be just fine, BTW.
Rookies have all the same injury & opportunity risks as vets PLUS the risk that they just aren't NFL caliber players.
To be more blunt: Vegas odds tell us that one of Fournette or Cook
will not cut it in the NFL/fantasy world.
Lest we forget... the the first two RBs taken were:
2008: McFadden; Mendenhall
2009: Shonne Greene); Knowshon Moreno (followed by Beanie Wells and then Donald Brown!!!... Shady was the 5th RB by ADP... WOW!)
2010: Ryan Matthews, CJ Spiller (followed by Jahvid Best and Montario Hardesty)
2011: Mark Ingram, Ryan Williams (followed by Daniel Thomas and Mikel Leshoure)
2012: Trent Richardson, Doug Martin (Followed by David Wilson)
2013: Giovani Bernard, Eddie Lacy (followed by Montee Ball... then finally comes Leveon Bell)
2014: Bishop Sankey, Carlos Hyde
With a very few exceptions, that's a who's who of fantasy busts. Sure, every player has questions, but give me a top ten proven vet any day of the week over these rolls of the dice.
Editors note: Before someone complains that I am cherry picking by not counting 2015 and 2016, I believe that an RB's value really cannot be determined until the third year. Prior to that, they are way to volatile and rankings are based more on perceived potential than actual performance. Gurley was #1 overall preseason... now he is in the teens at best (overall) and by the end of next year, could drop out of the top 40 overall. Another example, Montee Ball was a top ten overall ranked player going into his sophomore season and we all know how that turned out. If anything, I should have left off 2014 as well since Hyde has only a handful of fantasy relevant games in his first three full seasons and yet still commands a top ten RB ranking for some reason.
