I seem to remember going to some player of the year do at Springfield Park where Roy Carroll must have won some award - possibly in 1998 & he possibly got player of the season.
Anyway in his speech John Deehan mentioned that he'd earned the nickname George Best as a result of his escapades on their pre-season tour.
A little later on the SC did some "joke" awards & Gavin Johnson "won" one. I forget what it was for but do remember thinking that the prize (a yard of ale) was in very bad taste as there were rumours that Johnson was an alcoholic (I've no idea whether that is actually the case or not) & Johnson himself refused to go up to get it - Roy Carroll went up & necked it.
I don't know if he had any issues but alcoholism can be a gradual process that starts with just drinking to excess for pleasure, a laugh or just somet to do & before you know it, it has a grip on you. With Roy Carroll and what I heard and saw of him in his early days with us I always assumed that had been the case with him
