Talking about MLS with someone who specifically seemed nervous about getting mentioned in my blog, we discussed at length something that's a bit of a sensitive topic - the ethnicity of players and coaches in the league.
Basically, it's my contention that, (although I don't really know all the coaches of the league personally) no one is looking to discriminate. Soccer is the world's most international game, and both coaches and players are actually some of the most widely-traveled people who work regularly with a amazingly diverse group.
That said, I also believe that coaches feel comfortable with what's familiar. They're not going to stray too far from the roots of the style that they know and understand.
For many coaches in MLS, that style is that one similar to England's - an honest, direct and hardworking approach that emphasizes athleticism and a direct style on goal. The long ball or the work the ball up the wings and cross approach are both popular.
Slashing runs that break down a defense or tricky passes by a center midfielder are depended on less. Most MLS players are asked to multitask and play defense with at least the same energy given to building scoring chances.
On the other hand, the style emphasized by many Latin American squads is varied and often more creative. Argentina's Lionel Messi isn't depended on for his defense, for example.
Intrinsically, this makes it difficult for some players who don't play the English style to adjust to MLS, and they may find themselves benched a lot. A superlative player, such as a Carlos Valderrama or Marco Etcheverry, can overcome this, because they're good enough that a coach will throw caution to the wind and build a team around them and their skills - but otherwise, it's a bit of a square peg, round hole problem.
The coach is the one in charge, so ultimately, he'll pick the players that can best play his style. With so many MLS coaches influenced by the English game, that means certain decent, yet different players, never seem to catch on. That many happen to be Latino is mainly a distinction of style, not ethnicity.
Though Juan Carlos Osorio clearly has experience with the English game, having coached at Man City, and having received a coaching license there as well. Yet the Colombian-born coach has also coached in that country, as well as received a coaching license from Holland.
Hopefully, that all adds up to someone who is open to modifying the general MLS team template and putting something distinctive out on the field.
I realize that Chicago Fire fans are just hoping the guy wins, but to evolve the MLS game a bit, and to perhaps become a club that is unique and also welcoming an imaginative approach to the game, and players who fit in with that - that would be real progress.
