Well, Zagallo was an ex-player and took over the role as coach for the 1970 World Cup, and we all know how it went (pretty well), but that was a whole different era, a whole different team, and Zagallo is somewhat of a genius. Dunga, on the other hand, is not. Apart from lacking football coaching experience and not being THE greatest strategic player Brazil has, he dosen't have much of a leadership skill, even though he was the captain in 1990, 1994 and 1998. Terrible, terrible choice, made purely by desperation, with no real thought put into it. Sadly Scolari shows no signs of coming back from Portugal - ever - so I guess that's pretty much what we'll have, mediocrity. A coach nicknamed Cuca would be the perfect choice for the role, or... oh well, what the heck, even ex-Barcelona's Luxemburgo, but I guess we'll have to take Dunga at least for an year.
