There isn't anything easy about being a rookie in the NFL -- unle s your name is , apparently. The No. 4 overall pick in the 2016 NFL Draft and presumptive starting running back for the thinks he's got a pretty easy job.One of the "easiest jobs" actually, owing in large part to the team he plays for, which has one of the best offensive lines in football. Ezekiel Elliott: "I think I probably have one of the easiest jobs in America. I get to run behind the Jalen Lecque Jersey best O-line in America." Jon Machota (@jonmachota) He's probably not wrong. Elliott's job is extremely difficult because he has to adjust from the speed of college football to the speed of the NFL. He's charged with helping the Cowboys overcome major E'Twaun Moore Jersey deficiencies on defense and return to the 2014 form they showed when ran wild over the entire NFL. He has to spend his third downs protecting .It's not easy being the Cowboys running back, particularly when there are superstar expectations lingering over his head. But if you look at how Cowboys runners have performed over the past few years, it's understandable why Elliott feels the way he does. Look at the Cowboys rushers who have gotten more than 100 carries in a single season over the past three years:PlayerYearRush Att.YardsYards/RushRush TDDeMarco Murray201321711215.179DeMarco Murray201439218454.7113Darren Shawn Marion Jersey McFadden201523910894.563Murray was incredible, particularly in 2014, but the Cowboys decision makers were justified in the belief that they could plug anyone in behind that line and find succe s. McFadden topped 4.5 yards per carry for just the third time in his career, and the first time since 2011. The Cowboys front office was not justified in the belief that having no one to back up Romo would be a solvable i sue if the starting quarterback got injured, but that's another argument to have for another day. looked great in his preseason debut though! Drafting Elliott high in the first round goes against that running back philosophy, but it might fall hand-in-hand with the Devin Booker Jersey "protecting Romo" philosophy. Elliott is fantastic in pa s protection, something rookies typically don't excel at -- if he can play all three downs and keep Romo from taking shots, he's an infinitely valuable piece to add to the offense.Even better news for the Cowboys: he's almost "full speed" right now despite battling a hamstring injury but probably won't play in the preseason this week.Ezekiel Elliott: "I feel ready to go. I think I'll be back next week full speed." No Dario Saric Jersey game this week? "I don't think so." Jon Machota (@jonmachota) It's crazy to think of Elliott as the lynchpin for the NFC East, but it's entirely po sible his health and production could swing the balance of power in favor of the Cowboys. At least he's not stre sing about the job.
