The barrel was basically empty by 1996, the West Indies were struggling to identify any good batsmen other than Chanderpaul. Arthurton had a good start to his career and even scored test centuries against Australia and England, but was too inconsistent.
The fact that the West Indies failed to score at 4 runs per over when they had 8 wickets left going into the last 10 overs, indicates there was something else going on during that semi-final too, as alluded to by Richie Richardson since.
