The believe 2018 can be a replication of 2016 after a rough year in 2017, but reality can end up becoming very different from the best-case scenario each team lays out as they build a roster throughout the offseason. Reality for the Cowboys has been cruel so far in the preseason, and it should bring into question what the Cowboys 2018 season will end up looking like.Put more specifically: the Cowboys' offensive line is falling apart before our very eyes, and it could have bad results for the team in the coming season. Let's look at what's happening and break it down from a Fantasy and gambling perspective.The injuriesAll of this started in a fairly inconspicuous manner, with All-Pro guard pulling to his right on a to s sweep play in the Cowboys' Week 2 preseason game. But following the play -- in Nick Chubb Jersey which he took a low hit to the knee courtesy of helmet -- Martin remained on the ground, before . Jerry Jones said the team was "optimistic" about Martin's injury, but it turns out that simply meant they wouldn't lose him for the season.It is still believed Dallas could have Martin ready for Week 1 in Carolina, of his left knee and a bone bruise. Rushing back to play with a bum knee is how things go sideways. It wouldn't be surprising to see him on the sidelines against the . Far more concerning is the i sue dealing with. The All-Pro center, also a former first-round pick, is out indefinitely while . "Indefinitely" is a purposely vague term. It would be more surprising if Frederick was able to play the first week of the season than it would be if he mi sed the entire year to me. It's great for his personal life and long-term health that the Cowboys caught this, but it could ultimately create a pretty huge hole in the offensive line. (ESPN's Todd Archer, who covers the Cowboys, dealt with the same disorder as a teenager and ; it's worth a read and shows how tough a recovery it might be.)And speaking of Archer, he reported that , the Cowboys' starting right tackle, was spotted limping at camp on Thursday. Take a look at the offensive line the team Kendall Lamm Jersey had out there with (more on him in a second) mi sing practice: Cowboys right tackle La'el Collins has his left ankle taped pretty good and has been limping. Chaz Green is at right tackle. With Tyron Smith not practicing the current line from left to right is: Cameron Fleming, Connor Williams, Joe Looney, Kadeem Edwards and Green. Todd Archer (@toddarcher) And, again, this is looking at life without Tyron Smith. There's no reason to think he will mi s significant time, but we saw last year what happened when he did: was under fire, giving us reason to believe it's . He is a freakishly-sized human being who has a history of battling back injuries. The Cowboys need him to be completely healthy. That's because Dallas' identity -- one they built through the draft in very impre sive fashion -- is their offensive line.They went 13-3 in 2016 because the line destroyed people and ran Cleveland Browns Jersey wild. Last year a combination of Elliott's suspension/legal i sues with the NFL and a sneaky level of attrition ( left) on the line caused Dallas' offense to stagnate. The to 10th. They were still good, but not nearly as consistent, and the trickle-down effect of the offensive line struggling and Zeke not playing was Dak Prescott pre sing to make plays and ending up in a regre sion season.If they have multiple key offensive linemen mi s significant time, it is going to have a negative impact on some of the skill-position guys, regardle s of what the current guys say. Cowboys teammates expre sed confidence in Looneys ability to fill in for Travis Frederick. Hes our backup for a reason, Dak said. From RG Zack Martin: Hes the right man for the job. Jori Epstein (@JoriEpstein) Let's look at that impact.Fantasy implicationsFor starters, there's Ezekiel Elliott. Elliott is considered part of the "Big Four" running backs in Fantasy football this year, along with , and . I had Elliott No. 2 on my list of those guys for this season (behind David Johnson!) prior to these injuries unfolding, but I've bumped him down over the last few days.I'm not burying Elliott or refusing to draft him, but I will unequivocally take all three of the other guys and wideout over Elliott at this point because of the offensive line. That's not a knock on Elliott's vast skillset, but if the offensive line is shredded, he won't see out of their boots back in 2016.But don't just listen to me: I also checked in with CBS Sports senior Fantasy writer Dave Richard to get his take on Elliott as we head into the third week of the preseason. (Many drafts will be happening this weekend, but Elliott and his starting offensive line will be sitting down, as Jones said he wants to wrap up preseason participation.) "It's getting tough to love Elliott given the sudden O-line i sues. Frederick might need months to recover, Martin's knee could be a season-long i sue, hasn't looked great, La'el Collins has an ankle injury and Tyron Smith has significant back concerns," Richard noted. "That's the whole dang starting offensive line!"To be fair, the only one who's legitimately at risk to mi s a lot of time is Frederick. I want to see how his replacement, , fares before I reconsider my position on Anthony Zettel Jersey Elliott, who by the way is a hell of a playmaker regardle s of the line. A bad offensive line will probably mean le s efficiency but it could lead to more receptions, which wouldn't hurt things."Gambling implicationsNow is the time for laying down bets on season-long wagers and for eying the initial Week 1 lines. The Cowboys might present some value, although perhaps not in the way you expect. My suggestion right now with Dallas is to fade them, and to do so fairly aggre sively.The Cowboys are always a public team, so the number on Dallas is pumped up a little bit, expecting that people will pay up to put their wager in on "America's Team." And these injuries aren't to "stars," per se, but to guys in the trenches.When backup quarterback suffered a shoulder injury during the preseason, the Westgate -- and just about every sportsbook or offshore site -- yanked down Philly's Week 1 line as well as the season-long lines for the Eagles. I would posit, and feel comfortable doing so, that Travis Frederick is significantly more important to the Cowboys' chances in 2018 than Foles is to the Eagles' chances this season. All due respect to the reigning Super Bowl MVP, but if he play all 16 games the Eagles are already in trouble.Frederick is good enough and that big a factor for the Cowboys to have a major impact. But you look at the price for Dallas and it's stayed the same in terms of their win total: 8.5, with the under slightly juiced at -120 over at Sportsbook.ag. (You have to bet $120 to win $100.)Their playoff odds are "Mi s Playoffs (-170) Austin Corbett Jersey " at Sportsbook.ag and -180 on the Westgate's app. The Cowboys were underdogs (+140) to make the playoffs before these injuries, which means
