Two different eras so difficult to compare. Moze was just edged out of a spot from the 1991 under 20 world cup squad (he was one of last 3 or 4 men to get cut). Also there was the rumor of St Clair having issues with him, Sherwood and others (accusing them of having a "whiteboy" clique on one of the tours although sherwood and keeper gavin moze made de final squad ahead of tobagonian keeper Larry Parks).
Back to the question, I think he is much better than DeSilva but Sean will achieve a lot more than him because more opportunities are available these days.
There are a lot of other guys in that era such as Ivan Sampson, Darrel Edwards, Sean DeSouza, the Bennett brothers, etc who I think are better than guys who getting trials and contracts now but back in those days nobody was studying Trinidad until Yorke, Latas and Leonson put Trinidad on the map.
