There are occasionally suggestions that the reintroduction of the 8 ball over would speed play up and overcome the persistent problem of slow over rates. But the fast bowlers' union responds that this would be against their interests, particularly in some of the hot and humid environments that cricket is played. Advertisers also would be unlikely to welcome fewer between over breaks. So it is likely that the 6 ball over will remain. Unless of course the ICC thinks that something different should prevail because it has been used in T20 cricket.
Although his world wide readers will know that Fantasy Bob is a traditionalist in most things, he thinks that 8 ball overs should be used in evening matches to reduce the time lost through changing ends.
But in lower league cricket the 6 ball over can be the exception or at best a rough average. Many umpires have an uncertain grasp on the number of balls bowled in the over, having been distracted by any number of factors - some of them actually on the field of play. Signalling a four can plant the idea of four even after the first ball of the over. Some of course simply can't count and have no knowledge of numbers after 1,2......er 3. Some judge the end of the over by the boredom factor. Had enough? Must be the over. Then there are the wides and no balls - and in lower league cricket these can be a constant feature and it is a strain on the already stressed umpire to remember not to count them - or to allow only one additional ball. It would unduly strain these individuals to introduce 8 ball overs.
