IMHO, the biggest needed change to the SB code for Dallas is producing a solid pass rush and secondary. Our new and hopefully improved pass rush with Damontre Moore being a hopeful, along with Taco, Maliek Collins and Tapper should make some semblance of an impact.
The offense could also stand becoming a tad more dynamic and might end up doing just that with a few new tweaks like Gathers, Switzer and the Dak/Zeke duo being one year further along in their development.
Anything can happen, despite the C'boys' Super Bowl qualifying process still being in a developmental stage. I think it's more likely to occur in 2018 to be totally candid, although a surprise SB visitation this year would undoubtedly be welcome.
