A lot of people are questioning the attitude and fitness of players, but the fact is that our management and infrastructure is causing the main damage.Pitches don't encourage fast bowling at all, SG balls are being used here, which helps bowlers who swing the ball in the air, thats the reason why more number of bowlers are looking to become swing bowlers or line and length bowlers and not hitting the deck hard, why would a bowler bowl fast when he can pick more wickets by swing bowling?
Varun Aroon is the fastest Indian bowler and he bowls with good control, but look at his First Class record, there are many other bowlers who bowl much slower and look to swing the bowl and have picked up a lot more wickets.The schedule of the domestic matches is also quite hectic and demanding for the bowlers. There are 4 day games played every week, how is it possible to stay injury free in such a case?
And the worst thing with the fast bowlers is whenever they are in form, they are overused, they have to play the IPL, ODIs,T20s and Tests. Ishant Sharma is the best example of how some who can bowl 140+ with good swing, suddenly just lost his pace and became injury prone due to too much workload.
