over rates have gone down the pan over the last 20 years.I use to play "timed cricket" in Sunday friendlies. Started at 2 pm, in 2 hours 45/50 mins we'd expect to bowl around the 50 over mark. In return we'd get after tea 1 hour 15 minutes or roughly 20-22 overs + 20 overs from 6.30pm. Worked for a long time before and a long time after I started. All of a sudden it was a 1.30pm start because teams would bowl 40 overs in 3 hours.Bowlers have the same run ups, fields are much the same but many teams don't get on with it ie. spend time changing the field several times an over, idiot bowlers going around the wicket because they can't bowl straight. You get the idea.I once got my colts to bowl 20 overs in an hour in a friendly. No problems, just a bit of urgency was required. It's a brilliant tactic to bowl 4 overs in 10 minutes and watch teams panic when they realise they are running out of time.
