What does this mean? Why is it good?
Which bit don’t you understand?
Okay - he goes…
Every time he went in to bat he made ‘on average’ about 36 runs and he made over 100 runs six times before being given out. As a comparison the best batsmen in the world will average about 50.
When he was bowling to the batsmen they only made about 29 runs before he had them dismissed. As a comparison the best bowlers in the world average a batsman out every 20 runs or so.
To find an all rounder (ie, one who can bat and bowl) with good averages such as these is rare. as most players will either make a name as a batsman or as a bowler - rarely as both.
The quote then goes on to give his averages for the one day version of the game.
The captain of a cricket team has a lot on his plate, especially when fielding - what bowlers to use, where to place the fielders, and since in 1-day cricket each bowler has a limit to the number of balls he can bowl, the juggling of bowling order can be a worry. To be able to bowl well as well as being a captain is rare - most captains are batsmen, who don’t have to bowl. So a good bowling average as captain shows a cool head.
I might see if woolly can find the transcript of the famous radio sketch which explains cricket perfectly (well sort of).
Two points not already really clarified - test matches and one day games are essentially different games and the dynamics of play are different (a “good” test opener will often be a lousy one day opener because they don’t score fast enough).
Different types of bowlers also tend to have different types of bowling averages (due largely to the potential for their style of bowling to be belted to or over the boundary).
Is this the one, reprise?

That’s the one tavalla. I owe you a beer. 
I knew it was written in English, I just couldn’t figure out how! Thanks guys, and welcome to the boards, Swagman! I just have one more question:
How long would it take to paly a wicket? How many balls would be bowled in that time?
I expect the Aussies have gone to bed, so I’ll try to answer this one jiHymas. You don’t play a wicket you take one - if you’re a bowler. The batting side have ten wickets to lose (each wicket is equivalent to an out in baseball).
As BalmainBoy has said, in one day games each bowler is restricted to a maximum allotted number of overs (1 over = 6 balls), and in his best bowling performance in a One Day International (South Africa v India, Cape Town, 7 December 1992), Cronje’s figures were:
Overs 10; Maidens 0; Runs 32; Wickets 5.
That means he bowled 10 × 6 = 60 balls; none of the overs were “maidens” (no runs scored); the batting team scored 32 while he was bowling; and 5 batsmen were out due to his bowling.
Cronje took 114 wickets in a total of 188 ODIs. That’s not a spectacular record, but as other posters have mentioned he wasn’t a specialist bowler - the very best bowlers tend not to score many runs when it’s their turn to bat, and Cronje scored 5,565 runs in ODIs, which is plenty.
