I think we looked best with that 3-3-3-1. Deserved to draw or lose but we still got the better of the play for the most part. I don't see a huge reason to keep Fernandez in there right now. He does some nice things, but I don't think he's quite there yet. I don't love Rza's playmaking but he does cause some chaos in there with being able to win back the ball. The biggest choice is probably CCJ or Davis. I haven't liked Davis' game at all this year with the ball. HIs passing as just been awful in my opinion. That said, being the lone 6 when we are going with this formation is hugely important. CCJ is playing better than Davis right now, but Davis might be better for this formation. ANd I'm not crazy about CCJ farther up the field because I think his best traits are defensive. Murillo has been garbage defensively but he's good with the ball and I think this formation protects him more so willing to give him another run out there.
Here's what I would go with:
This is a good formation for us. We were good in it 2 years ago and then we didn't have the horses on defense to really play it. Now we do. Tarek may even be pretty good although that error against Cinci was huge.
