I predict Super Bowl literally every year. I had reservations in the preseason about this roster, that through 3 weeks have been proven correct. You guys are horrible though, they're not that bad.
My primary complaint was lack of depth on offense behind Gronk/Edelman, the linebackers being slow, and no depth behind Flowers and Gilmore.
The first complaint was validated, showing that we really need as second target for Brady out there to be competitive. He's coming back. The midseason trade for Gordon was massive if he can put up ~600-700 yds, and gives them three real weapons instead of two. That also means that if one of those three goes down, we have some hope of fielding a decent offense.
The linebacker problem is an inescapable weakness of the roster. The secondary sucks without Gilmore and the pass rush sucks without Flowers. We have seen the latter point in action. God help us if we see the former. This is why I think this roster is fragile as heck.
That being said, with a few real threats on offense (versus the 1 (one) they had today), and the return of some semblance of a pass rush with Flowers, I think they can still be competitive/win a Super Bowl. If injuries hold their roster back too much, they probably cannot. The roster is simply thin compared to years past.
