How do you know this and how do you definitively make that statement? Garrett's on the sideline and if he felt that Weeden was a better option at that time, then the Owner/GM coming to the sidelines in his make or break contract year to "inform" him that Rommo is available could very well alter his thought process. I'm not saying this happened, but no one can definitively say Jerry had no impact, especially considering he's done this in the past:

"Jones says he doesn’t tell Garrett who can play and who can’t, but he did want to make sure Garrett understood that quarterback
Tony Romo didn’t need to take any chances by playing in an essentially meaningless game against the Eagles.
“That’s Jason’s decision, but he doesn’t need to be making that one by himself,” Jones said. “So I wanted to, very briefly, step down there with just a few minutes gone in the first quarter, sit there and say, ‘Here’s the lay of the land. Romo’s got a hand injury, but it looks like we’re going to have him for New York.'”
And if Jones thinks his coach might not know the lay of the land, Jones is going to make sure his coach knows the lay of the land. That’s going to be the case as long as Jones owns the Cowboys."
For the record, I can't debate the decision. Had Weeden gone in and thrown a pick, we'd be talking about how the HC sat the franchise QB with more 4th quarter wins than any active QB. But my point is that Jerry going to the sidelines and Garrett knowing how Jerry may feel about a certain situation can certainly impact his decision making process. This is uncalled for during the game, especially in such critical moments.
