Let G be a finite p-superperfect group. A conjecture of F. Cohen 
suggests  that \Omega BG^p is resolvable by finitely many fibrations over 
spheres and iterated loop spaces on spheres, where (-)^p denotes 
the p-completion functor of Bousfield  and Kan. We produce a 
counter-example to this conjecture and discuss some related aspects 
of the homotopy type of \Omega BG^p.
