IMHO the problem with a lot of 1v1 dribblers is that they think they're 1v3 dribblers. I only saw the 2nd half of the Germany game but I saw a fair amount of dribbling into heavy pressure where the ball was lost. If your trying to beat 3 players, 2 of your teammates are wide open, likely in close proximity...get rid of the freaking ball. That's soccer IQ.
From my armchair, I think speed-of-play and gaining a numerical advantage are two of the most important elements in successful soccer. Dribbling can slow down the play and when you dribble into pressure your at a numerical disadvantage. Dribbling has to be used judiciously as a tool and not as an overall tactic. If you look at the most effective dribblers they dribble at the defender at speed with rarely any fancy moves, they beat you by getting you off balance and blowing by you (see Messi). Once a dribbler slows, stops, or pulls the ball back, they've lost most of their advantage and the defender recovers and simply "stands them up". At that point they have to rely on some fancy move with a low percentage success rate. The greatest advantage of a 1v1 dribbler is the threat that they will beat someone. For whatever reason, coaches and players fear getting beat 1v1 much more so than getting beat by a pass, so they mark up that player with multiple defenders which then gives you a numerical advantage which can be exploited by a smart player.
In the context of this thread and the article, 1v1 has been defined as someone who can beat a defender on the dribble. To me a true 1v1 player is much more than that. They win 50-50 balls, they can maintain possession long enough to create space and make a great pass, they create space so they can receive a pass, they can pressure an attacker into making a bad pass, etc... It's someone who can be successful offensively and defensively while under pressure from a single opponent regardless of what the battle may be.
I'm all for possession, because possession is proactive. If you have the ball you get to make the decisions. Given the option of having the ball and making a good decision vs. not having the ball and trying to make your opponent make a bad decision, I'd choose the former. However, possession without a purpose and/or pressure, is just possession for the sake of possession and probably isn't any more effective than "parking the bus".
