More likely it's Sacha with Davis or Adams moving to his spot. It would be for the same reasons we traded Dax and not Felipe this season, age and money. Plus, has Marsch ever been a head coach without Felipe on his roster?
I bet we trade Felipe this off-season and let Adams slot into that CDM position, and let Murillo play the wingback position.
Adams could certainly play Felipe's role in our current formation, but it would be a waste. Felipe's back there by himself, so he has to stay home more than you'd want Tyler to. In the ole 4-2-3-1, one of the two deep lying CMs spots is a great place for Tyler, assuming the other stays put to shield the backline.
