I've been giving some thought on how we can improve the midfield, which is perhaps the biggest weak point of the team right now. I think the best option is to move Fabian Johnson and Geoff Cameron into the midfield and rely on other players to hold down the back.
We need a new center mid to partner with Michael Bradley as Jones and Beckerman age. Cameron has been starting there for Stoke the past couple of months (prior to his injury). Having Geoff in mid would give cover to Bradley as he moves forward. Cameron will only be 31 at the time of the next World Cup.
Similarly, Fabian Johnson plays primarily at LM for Borussia Mönchengladbach, and he's been killing it there lately. We don't have anyone else established enough at that position to justify moving Fabian back to defense.
So, if those two move up, who plays in back? Johnson has been used at RB, but with Yedlin getting good time in England, it seems time to let him lock down that position. Cameron has been used in the middle, but we have John Brooks who can team with someone like Gonzalez, Besler, Alvarado or whomever else is in good form - also Miazga in another year or so. That leaves LB, which is always a question, but there are several serviceable candidates in Ream, Beasley or Villafana - maybe even Lichaj. The best argument for playing Johnson in back might be at LB, but I still think better to have him in midfield.
Starting lineup...
[Dempsey] - [Altidore/Johannsson/Morris]
[F. Johnson] - [Bradley] - [Cameron] - [Bedoya]
[Villafana/Ream/Beasley] - [Brooks] - [Gonzalez/Besler] - [Yedlin]
[Howard/Guzan]
