I think Horan has to see the field. Our midfield shape is stronger with her in there. If I were the coach and not an out of shape, clearly expert armchair ummm..... QB?(What's the footy equivalent of this?) that's commenting while sitting in front of his computer, I'd do something like this....
O'Hara Dahlkemper Ertz Dunn
Lavelle Mewis Horan
Heath Press Rapinoe
I feel like Dahlkemper/Ertz gives us two CBs who can play out of the back. I like Sauerbrunn's defending, but she doesn't have the same passing skill of these two and she's been a bit slow to the ball a few times.
If you move Ertz to CB, then Mewis becomes our best option at 6, with Horan playing the 8 and Lavelle being a hybrid 8/10.
Press starts over an injured Morgan who was clearly a step or two slow. I'd also consider Press over Rapinoe and starting Lloyd, but I think that'd be better as a halftime/50 minute change if needed as Lloyd doesn't have the legs for 90 anymore IMO. Press gives us speed in the attack and those through balls that Morgan and Rapinoe watched go beyond the end line have a much higher chance of finding home if she's the one chasing them.
