I think this boils down to is 1) LD's sabbatical was a questionable move, 2) LD is not the player he was before due to age and maybe burnout, 3) even so, LD at 66% is still likely one of the top 23 US players, so 4) we hope that Klinsman made the decision based on LD's fitness and or how he fits into the team and 6) not a personality clash between LD and Klinsman and 7) this decision will be under the microscope on the Cup kicks off and Klimsman will be praised as a genius if the US gets out of group play and will be shredded if not whether or not LD's inclusion would have impacted the US team's fate in the group of death.
PS - If the US advances out of Group G, they will face the first or second place team from Group H (Belgium, Russia, Algeria, S Korea). Belgium is scary but unproven. Algeria and S Korea should not be underestimated. Russia has skill; but, was lucky to make the Cup. Not a bad chance for the US. If the US advanced to the Final 8 as the first place team out of Group G, the US would play the winner of Group E (Switzerland?) against the second place team out of Group F (Nigeria?), again, winnable, though Switzerland is a solid technical team; but, may have issues playing in Brazil. If the US advances as the second place team out of Group G (a more likely scenario), the US likely has to deal with Argentina (likely Group F winner). Not a good match-up. Still, I would want the US to win just to shut Maradona up. Hope the refs have learned what an offside call is by then. Losing to Argentina in the quarterfinals would have to be considered a good result for the US.
