Five games remaining ...
Skins
@Giants
@Raiders
Seahawks
@Eagles
Romo was definitely making a homer call.
Yes, if Elliot was playing for all of these, 4 or 5 wins would be quite possible. It's not a daunting remaining schedule. But considering Dallas has scored an average of just over 7 points the past three games (minus Elliot), there's no way they can win 4 or 5. Granted, he'll be back for the last two.
I'm guessing Washington will be favored in the next game. Though not by much, as they are really banged up. "Should" beat the Giants, but that game could go into OT tied at 0. At best, a coin flip as to who wins the Raiders game (Oakland is probably the slight favorite at this point).
And then Elliot returns -- but the last two are the toughest games regardless. It's possible that the last game for the Eagles is meaningless, and Philly plays its scrubs. But it's still a close enough race, that Philly may need to win that to maintain home field in the playoffs.
As of today, Dallas probably has a better chance of losing its next 4 or 5 games than winning. Most likely, they'll win between 1 and 3 of their remaining games.
You mentioned the Cowboys receivers. As I mentioned above, it's surprising to me just how much Dez has fallen. He's now no better than a #2 WR. And the rest of the receiving corp can only be good if he's a threat. And he's not much of one any longer.
