Reliable: Usual suspects, most of mine have been mentioned.
Unreliable: Julian Darby - seemed to have a decent eye of goal, and his build up play was good sometimes, but defensively...clang, clang, clang!
Gary McSheffrey - peaked early in his career, or he just couldn't be relied on generally, when he came back. Blew hot and cold like a mofo.
David Rennie - again, scored a couple of decent goals, had a good attacking range of passes, but defensively...sheer plop.
Controversial one - Noel Whelan: this boy had the talent, the skill, the instincts and the vision to be a regular for his country, at the highest level. Pissed it all up the wall though, and his fitness levels were as low as his motivation for 95% of his City career.
David Burrows - never liked him, personally. Looked confused and out of position constantly, passing was terrible, bottled crucial tackles. A very poor, overrated player.
