Actually I (stupid, yes I know, but just not a pessimist by nature) do have pretty high expectations for 2018, due to several factors:
1. No Zeke suspension hanging over the team's head.
2. Dak had problems, he has gone through them so he knows what to work on.
3. Wade Wilson is gone, I saw no evidence he has a good quarterback coach, Moore is at least "fresh blood"
4. At this point at least, no suspensions looming for Lawrence and Irving.
5. J. Smith showed flashes of very good play, don't think he was nearly recovered from the knee injury at the start of last season but by camp he will have had plenty of time to heal up.
6. The Cowboys' history for the last 4 years shows a 10 or better win season followed by an under 10 win season. Under 10 in 2017, so by history this year will be over 10, which means good chance to make the playoffs. Have to get in the playoffs to have a chance to compete for the SB.
7. The last few years the draft picks are much better - Martin, Frederick, L. Collins. Awuzie for example. Don't see why that shouldn't continue. So should get some help in 2018 via the draft.
8. Speaking of Awuzie and the other rookies, they "got their feet wet" in 2017, with camp (especially for Awuzie, who missed most of camp) and pre-season, they will be better prepared for this upcoming season.
9. New coaches, fresh ideas will be introduced to the team, I think the coaching staff had gotten stale over the past few years.
10. Last year doesn't have to have any relation to last year. Who thought the Eagles were primed to be SB champs? Few, if anybody, but they are. Cowboys can be much better, no point with doom and gloom forecasts, no telling what can happen in 2018
