This team could beat USA, why not. But they could very well lose as well. In 7 games I would still bet 4:3 for USA probably.
On other hand against USA it should be more of athletic and fast lineup, I agree with Southpaw.
PG. T. Parker. Rubio.
SG. Rudy, Navarro (just to have one pure shooter), Batum (to use as a big guard)
SF. Kirilenko, Iliasova, Kleiza
PF Pau Gasol, Nowitzki, Ibaka
C Marc Gasol, Noah (or Mazgov, Kaun, Koufos)
This team would fit more against USA , IMO.
Both teams are really bad. Guys, you can't beat best American players if almost all of your players are of the same type/mentality - only generally worse in quality, sometimes slightly, sometimes drastically. So any European team who can give Dream Team a really tough competition (not only in one game but in the series) must be composed mostly of the players of different, non-NBA mentality, players who can surprise them, who are playing another type of basketball. Yes, most probably in order to be successful this hypothetical European Team must bulk up their roster with 2-3 European NBAers but only with the ones of the highest individual quality and some brains left. But you made up teams of Ilyasovas, Ibakas and Noahs which is really laughable. A team like Italy of early 2000s with all their shortcomings would be more successful than these ones just because they were playing traditional continental basketball and weren't relying on athleticism or run'n'gun acrobatics. You can beat Team USA in its best roster regularly only if you are completely different thing from them, if you are going to play 'their' type of basketball then you are doomed because they just have more quality and it's adapted to this type of basketball. You can't run faster than them but you can think faster than them. And this is the only way to win.
So my team would be something like this:
Milos Teodosic - Vassilis Spanoulis (no braindead Parker, with all his stupidity, 'I shall win it all by myself'-mentality and awkward shot-selection he is atrocious in internationall basketball; no Bricky, are you serious, he sucks for the last half of the decade continuously, turnover-machine who can't nail it when his life depends on it... what is the PPG he averaged in Barca - 5 or 6? and he is no Prigioni who can have 2 points in a game and still have efficiency of 20 with 10 assists and 7 steals; Shved... well, all of you just seen him in London, the guy has no brains at all which combined with the mediocre but visually flashy offensive prowess made him really suitable for NBA but not for this team)
Juan Carlos Navarro - Vitali Fridzon
Rudy Fernandez - Fernando San Emeterio - Andrei Kirilenko (the last one for his individual defense and physicality, still his stupidity always costs his teams more points than he give 'em with his great rebounding, steals and hustles)
Dirk Nowitzki - Viktor Khryapa - Joel Freeland/Milan Macvan (someone young, enregetic and with the good mid-distance shot)
Pau Gasol (he will play center and not PF in order to be the most effective for this team) - Sofoklis Schortzianitis - Timofei Mozgov (the last two are needed for the physical domination because one of the main American weaknesses these days is the lack of the offensively capable massive centers aside from Howard)
This team looks like a not very comfortable match-up for Americans. They still have more individual talent and winning mentality but this team can exploit their weak sides and is most effective in the type of the basketball non-convenient for US players. This team can vary the tactics pretty well - with Mozgov it can play more p'n'r-based style (and even with unorthodox Khryapa-Mozgov combination where the first takes the role of a point forward), with Sofo it can intimidate their opponents with the massiveness (is there such a word?) and power in the paint, both of its main SF (Rudy and San Eme) can play as SG if needed and they have a good combination of quickness to stay close to their opponent on defense and size to try to use it against smaller opponents in offense (and generally they are very well-rounded players), most of its big guys have decent to good three-point shot - so they can't be left alone on the arc, Teodosic, while he is a real psycho and hugely mentally unstable, has one of the brightest 'basketball brains' out there and is an epitome of the real European PG who could be a great floor general, and this team has enough individual offensive talent to compete with the best both in the backcourt and in the frontcourt. A very influential aspect of the possible success for this team would be a deep rotation (current Barca-style) with none of its players, Dirk and Pau included, playing more than 25-26 minutes per game.
Oh, now I realise that my team is composed from 13 players but let it be, it's too late to fix it 'cause the post is written from the perspective that all of them are in the roster.
I'm not sure that this team would most probably beat Americans (they are one tough opponent) but it looks much more ready for it than the team composed of Parker-Rubio-Shved-Ilyasova-Ibaka-Noah type of players.
