Reading about Berget and fans of his are saying he's actually best on the wing because of his incredible work rate. I'm predicting this for an opening day lineup:
F | Berget, Villa, Harrison
M | Maxi, Herrera, Ring
D | Matarrita, Callens, Chanot, Tinnerholm
I think Berget may end up starting at LW while Medina competes with Maxi for the #10 spot and backs up LW. Because Vieira likes to motivate his youngsters by withholding playing time, Maxi probably starts opening day.
Tajouri primarily backs up Harrison, and Lewis and Wallace round out the attackers. Medina is first off the bench if Villa sits, when Berget plays up top. But in general, everyone rotates pretty frequently.
In the midfield, we are still missing the player that competes with Herrera/Ring and provides depth.
On defense, I assume Hountondji is the third CB until he proves otherwise.
