The greatest of cricket commentators, Richie Benaud, once said that captaincy was 'Ninety per cent luck and ten per cent skill - but don't try it without that ten per cent'.
You could, by extension, say that success in cricket as a whole needs ten per cent of luck at various times.
Take Derbyshire this summer. We were all set for a fun-packed season, in which our gun fast bowler cut down opposition batsmen in swathes, only to find he turns up with an injury, which effectively ruled him out of things until the end of June. To compound this, our other fast bowler, Will Davis, after a couple of sparkling displays, picks up a side injury and is ruled out for a similar period.
Luck with injuries, tosses, the absence of star players from the opposition due to international call ups, catches that you just make by the finger tips, rather than going to ground by similar margins, getting the right blend in the dressing room, winning tosses in wet conditions - they all play a part. However well Leicester City played to win the Premier League, they had few injuries and were able to play a settled side, while the 'big guns' all had seasons where they had to rebuild, or struggled to do the same.
It has been challenging for Billy Godleman and Kim Barnett this year, without doubt and had that ten per cent gone their way, I suspect that supporters would be a little more content than they are right now. By the same token, there have been a few situations when the requisite intensity wasn't there, while it is probably safe to say that our young seamers haven't all progressed as we would have wished. Had they done so, the loss of Viljoen and Davis would not have been so keenly felt.
On the subject of good fortune, I feel a little for Harvey Hosein today. He has done little wrong in the seconds and has scored steadily, if not spectacularly. At the same time, Daryn Smit has kept wicket nigh-flawlessly, having taken over from Gary Wilson when he went first to international commitments and then returned with a knee injury.
Yesterday, Harvey scored an unbeaten century for the second team against Worcestershire and, were there a game this weekend, may have played himself into it, especially when Smit himself sustained an injury in the final innings against Northamptonshire.
Yet there is no game for the senior side for another eleven days. Between times, Smit will likely get fit and Harvey can only press his claims by scoring runs and keeping well in next week's scheduled game against a likely strong Yorkshire second team. By the same token, he then only has the game at Cardiff, followed by the Chesterfield cricket week, before the T20 starts, not currently his game.
As things stand, his route into the side appears most likely either as being deemed a better wicket-keeper batsman than Daryn Smit, or a more in-form batsman than Alex Hughes, ironically the two batsmen who came out of the Wantage Road defeat with their reputations intact.
See what I mean about luck?
