Five U.S. matches over the last month has generated significant movement on the U.S. depth chart – perhaps more shuffling than in any month-long stretch in Jurgen Klinsmann’s time in charge, which is now approaching two years.

Over A few days we’ll continue to examine the U.S. depth chart, making our best educated guesses at how things stack up on Jurgen Klinsmann’s big board inside the manager’s Southern California offices.

Next up: SECOND FORWARD / ATTACKING MIDFIELDER

Looking for a reason the upcoming Gold Cup could be important, why the tournament could be quite influential in next year’s selection of a World Cup roster? Just look at the United States’ “second forward” spot, what could also be the attacking midfielder position with a minor tweaking of roles.

This is Clint Dempsey’s spot. We all know that. The current U.S. midfield construction in is largely about putting a couple of individuals in their best roles, namely Michael Bradley and Dempsey. (We talked about Bradley and his linking midfield role here.)

Dempsey is not a classic creator; he’s closer to a second forward who is licensed to freelance, to find the spaces on a given day, sometimes further out wide, sometimes closer to Bradley or sometimes closer to first-pick striker Jozy Altidore. Largely, it’s all about Dempsey being hard to find so that his slashing and dashing and arrival into goal-scoring position lands with maximum offensive impact.

How someone else might attack the role is presumably up for interpretation. And there’s the rub: there is no clear “someone else,” although there are certainly some intriguing choices.

So many U.S. supporters badly want to see Stuart Holden folded into the attacking mix, and he might indeed become a legitimate second option here. But …

Holden still must demonstrate progress in this long recover process. That’s where the Gold Cup comes in, obviously. Besides the obvious opportunity for assessment, a healthy and productive Holden could be better served coming in from wide areas. Or he could become the ultimate, utility midfield substitute, capable of effective function at any of the interior or exterior roles.

Either way, a “change of pace” man would be nice, eh? Someone who could provide something different in midfield if Dempsey needs to move further upfield, closer still to Altidore.

So, bring on the Gold Cup!

Is Joe Corona ready? Can Graham Zusi create from those central areas? (Although we are less likely to see that in the Gold Cup.) Can Jose Torres re-shape his image in the national shirt? Klinsmann keeps asking Torres to be more assertive, to kind more ways to impact the game, but the Tigres has continually fallen short.

Is Benny Feilhaber still any kind of option? Can Sacha Kljestan be useful in that specific midfield position, himself a “utility knife” type.

And, yes, there is the Landon Donovan factor. Reports are out now that Donovan will, as we all expected, be part of the Gold Cup roster. Left to be seen is whether Klinsmann wants Donovan to work the wings or the interior – the national team’s all-time leading scorer has toggled successfully between both spots throughout his long career, in league play and internationally.

Best guess: Donovan’s role is tied to Holden’s progress and where Klinsmann sees the Bolton man’s best fit.

Can we just say it again … Bring on the Gold Cup! Important questions are begging to be answered.
