I don't think we really know that yet, of course that's subjective, but whether he is or isn't kind of isn't the point.
It's fine to say you want to get rid of Foles. You don't like him, that's fine. But what's the better option?
Vick is on the downside of his career, he's expensive, and he may very well be part of the head-case issue that this team has become. So right there are three reasons not to bring him back. But even if you do, what's your long term plan? Use him for a year, maybe two, when you draft a QB in this year's up coming draft?
If you're going to do that, Foles would be cheaper. He also has arguably more upside to him as you've seen Vick's ceiling, but there's no way anybody has seen that from Foles.
But again, you don't like Foles so fine. You get rid of Foles and you get rid of Vick for any of the half dozen reasons there are to let him go.
Now what?
The QB talent in the draft this year is shit so you don't waste a top pick on that. Maybe you reach for someone late, but really if you're looking for a QB in the draft you want to look at next year.
So you look at free agents. Who's available that you really want? Alex Smith? How much different from Nick Foles is Alex Smith, really. The only time Smith really played well was under Harbaugh. Under every other coach he was mediocre at best which suggests something about the system, the coach, or both—neither of which we have.
And free agent QBs cost money. You have to invest in these guys not for a season, but as if you're looking at them as long-term solutions. What available QB do you want to spend a bunch of money on and name the Birds' starter for the next three to four years at least—and don't say Joe Flacco because he's not going anywhere.
This is less me making the case for Foles than me making the case against going QB shopping this season. The market sucks at that position. Wait until next year there and the options will be better.
Meanwhile, nobody is going to give us shit for Foles right now, even Fat Andy knows that. If—and I grant you that it's a big if, but if Foles were to go out and have a solid season, and Chip still didn't like him, at least then he'd have value that we could move. And we could move him at a time where the options to replace him would be better than they are right now.
