Not all of the talking heads on the four letter and other networks are Dallas haters, some call it like they see it, and do have some expertise, especially the ex-players.
Sadly what the ones that aren't calling for Dallas to do much have based their views largely on reality, the simple fact is that Dallas played once again in a weak division, got to play the terrible Falcons, just squeaked by the non-playoff Vikings, needed overtime to get by the not-at-the-time playing well Pats, lost to the non-playoff Broncos by a lot, and lost to a Cards team that lost 4 of their last 5, with the one win being over us. Losses to the Cards and Broncos at home, no less.
Even if they get to the NFC championship game, likely it's at the Packers, where they seldom win.
But having said that, have to keep some things in mind:
1. Covid is still around, what if they get to play the Packers and Rodgers is out with the Covid? Or all the other playoff games Covid ravages the opposing teams? I suspect it's entirely possible Covid will have a big role to play in who wins the SB, though teams will probably self-quarantine a lot.
2. It's all about matchups, Dallas may get great matchups in all their games.
3. Really there's no team that has dominated all season, all have had their "oops" games, the playoffs are one and done, an off game or some funny ball bounces and teams like the Packers can fall early.
So there's really no reason to be greatly optimistic about Dallas this year, now with Gallup out, T. Smith having off and on physical problems, and there's nobody to "plug in" at LG, etc., weak spots on the team will remain weak spots. Good teams/coaches know how to exploit those weaknesses, are our coaches up to the task?
My view is watch and what happens, happens, no expectations, one way or the other...
