Deano, deffo the best keeper I've seen and I loved Alan Kelly. Trace was decent, particularly in his younger days, but was prone to the odd moment of rashness, a bit like Paddy Kenny for those that didn't see Trace.
Kelly was arguably better at commanding his area, that I remember was Kelly's strength although he was excellent overall, but shot stopping wise there's no better than Hendo. Overall, Hendo the best, Kelly 2nd and I'd say Paddy Kenny 3rd, solely because Trace had more errors in his game than Kenny (who himself had errors as I say!), but Trace was excellent at commanding his area in an era where punching was not commonplace.
When I say Kelly was better at commanding his area than Hendo, its a different approach now than it was in the past, and tbf to Hendo, his decision making on when to punch or when to claim from a cross is impeccable, and who knows how many goals are saved from Hendo preventing an opposition player from heading the cross.
Got to give a mention to Mel Reece too - bless him, we'll never know how good he could have been of course, that was tragic and such a sad loss.
