I'm no expert on this subject, but I would think Antonio Carbajal should be at least in the reserves. He had appeared in 5 different World Cup tournaments which was a record for 32 years until Matthäus in 1998, I dont know if thats enough to put him in there but its certainly impressive.

I also always thought Brad Friedel was better than Tim Howard but I might be in the minority there

Carbajal was definitely one of my potential choices. I wouldn't argue adding him to the reserves, replacing Forrest or Keller. About Friedel and Howard, I consider them on the same level but given that the latter was ultimately chosen for the best XI in the last USA all stars update, I guess it makes sense to have Howard over Friedel.

I put that down to Howard simply having more caps than Friedel, but from having watched them both many times in the Premier League I would take Friedel. He always seemed the superior keeper to me

Carbajal should be in first team here, I don't see a single reason why Ochoa should be selected over him.

Anyway, returning to this team: If you call the team North America AS, then Mijnals shoudln't be in. Suriname is part of CONCACAF but not North America. If he's in, then he's a strong candidate for first team - like Morgan and even Balboa.

Your suggested team has four RBs, while LB position is only covered with Davies. Of course Stalteri could play there but he was primarily a RB, not a LB.

should be removed here, he was long time French international and shouldn't be here for playing some unimportant friendlies when he was already 41 years old.
Bailey can be in reserves, despite playing for Leverkusen and Villa he always has struggled with consistency and never was (and probably never will be) a strong player who can lead a team. I'd replace him with either Delapenha (don't know why he isn't in reserves in your team, he is a no-brainer here) or Lozano.
I also don't understand why Negrete, Cardenas and Casarin are removed at all, especailly considering the names who are in reserves for example. You may debate if they should be in first team or not (although it is IMO a fact that both Negrete and Cardenas were better than Ruiz, de Guzman, Bradley or Hutchinson) but they're a must for reserves. Same goes for Caligiuri btw who I'd rank much higher than Alexi Lalas. From Trinidad Carlos Edwards and Kenwyne Jones could be considered here as well, maybe instead of Roberts. Frank Sinclair also should be taken into consideration for defense.

I’d definitely have Gustavo Peña in the first team, IMO he’s the second best Mexican defender after Marquez and captained Mexico at two World Cups. Also I guess you want some kind of variety of nations represented but it seems strange to see guys like Roberts and Goater in reserves when Luis Hernandez for example isn’t there. Likewise Blanco was a much better player than Dely Valdes or Bailey.

Who do you suggest to add to have another LB?
