The Australian batting of 1993 and 1993/94 was almost certainly the strongest of their 1989-2006/07 period: Taylor, Slater, Boon, M Waugh, Border, S Waugh, Healy. Over the course of this year, each of these players averaged 44 or more, and all bar Slater (a mere 74) played over 100 Tests. Thereafter, there was always at least one hole in the batting, though it came very close to being filled in 2004 (Langer, Hayden, Ponting, Martyn, Lehmann, Katich, Gilchrist - just a shame this only played together once).
The only holes the Australians had in 1993 and 1993/94 was in the seam-bowling. McGrath only became Test-class in 1995, and Hughes, who had been an excellent bowler for several years, essentially had his career finished in 1993 by a serious knee injury. McDermott missed 1993 with a twisted bowel (
).
If Hughes had not suffered the knee injury in 1993 and McDermott the twisted bowel, and if Reiffel had not been so injury-prone all career, the attack (McDermott, Hughes, Reiffel, Warne) would've been almost as good as the eventual best (McGrath, Gillespie, Kasprowicz, Warne) which played in 2004 and 2004/05.
Now just imagine Donald, McDermott, Hughes, Warne. If that'd been available, it'd have been bettered by 2 or 3 attacks at best in history.
