There was some disagreement on if Baker’s hit on Foles was legal or not. The NFL has come out and said that it was legal, he shouldn’t have been flagged or thrown out of the game. Here is the quote via PFT.com.
“Baker didn’t do anything wrong with that hit,” Vincent said. “When you look at the rule, he didn’t do anything illegal. People can say it’s a cheap shot and you can talk about whether it might fall under unsportsmanlike conduct. But when you know the rule and you look at the play, he didn’t hit him in the head. He didn’t hit him in the neck. We looked at it. I looked at it very closely. He’s not going to be fined for that.”
So, you can debate if the hit was unethical, you can’t say it was illegal.
