2008 was such a crazy season. You could do a doc on it. Between the hot start that had Dallas atop everyone's power rankings after week3 (thanks to TB12's being out all year), TO's inexplicable intent on dividing the locker room, PacMan Jones's nonsense, Romo's injury (leading to the ineptitude of Brad Johnson, and yes - BROOKS BOLLINGER!), and the famed December Collapse, it was a weird, wild season that ended in tremendous disappointment. Romo didn't help things by being human and honest exclaiming that if 44-6 was the worst thing to happen to him in life, he'd be ok. Remember how fans reacted to that? Imagine Dak doing that in 2019 with social media and the Hot Take TV Landscape (which was just in its adolescence in 2008). Yikes.
Aside from 3-0, I don't see many similarities between 2008 and 2019. If there was ever a WR that was the anti-TO, it's Amari Cooper. Dude plays chess, runs his businesses, chills out and then balls on Sundays sans drama. The leadership is better inside the locker room. Zeke and Pollard >>>> Barber and Felix. The OL is better. The DL is probably the same (that 2008 DL/OLB had Ware, Spears, Ratliff, Hatcher, & Ellis). The secondary is better. The LBs are maybe the same (different schemes, so...). That 2008 teams handled adversity as well as a 3 year old being told he can't have a bag of fruit snacks. Based on 2018, this team handles adversity much, much, much better.
