Zidane 6ft1 and Steffan Effenberg 6ft 2 might disagree
Berbatov, Zlatan - also fairly useful and 6ft plus. Dennis was 6ft. Kanu 6ft 4 Were the invincible world-class? Yaya Toure 6ft 2
(I did get the irony in the original post, btw, but made me think of which players have "quick/good feet for a big man")
