Cricket has bees so fast now, as we can only see show from the batsmen side, but in the past their were bowlers who bowl like a speed of 150kph and we have seen them they have long hairs and when they entered the ground mostly the batters on the ground will be frightened as we can saw that Shoaib Akhter from Pakistan's Team. Not only he there were too many these days, we have also seen Bret Lee when he came to bowling mostly the batsmen will also be in the pressure position. Also Dale Steyn was one of the best bowlers of his era.
But now we didn't see the charm in the bowlers and we can't see those bowlers who have some long hairs and have some stamina to bowl like what they have to do in the past against different teams. Now we can only see sixes everywhere and runs everywhere.
There are a few bowlers who can clock 150 kmph nowadays. Mark Wood, Mitchell Starc, Jasprit Bumrah, Adam Milne, Lockie Ferguson and Anrich Nortje are a few examples. But Lee and Akhtar during those days went up to 155-160 kmph. And they had better skills and wicket taking abilities when compared to the current generation of fast bowlers. Also, the focus has shifted to T20 cricket from test cricket. That means that the bowlers try to be as economical as possible and they are not willing to risk too much to take the wickets.
