Vaibhav has a question:

"I wonder if there is any way to practice improving reflexes against a fast bowler's release?"

There are many ways to improve your reflexes, but not many of them will make a difference against a fast bowler.

That's because the reason you are slow to pick up line and length is not the result of slow reflexes.

Hardik enrolled on my course, and had a follow up question:

"I used to spin a ball big, but then I tried to learn the wrong one. So I kept practising but then I lost my leg spin. How do I get that my leg spin back and then learn to bowl wrong one?"

Oh boy. That does not sound good!

Think about the phone you owned 7 years ago. I'm willing to bet that it didn't do much more than be a phone.

Then the iPhone arrived.

Since then, think about how much mobile phones have progressed. They are now small computers that many people rely on to run their lives. I know I do. It's evolved fast.

This week's winner of the Cricket Show podcast question competition is Jittu. He wins a free coaching course from PitchVision Academy.

The winning question was:

"ECB have changed the way that coaches get qualified, and I was wondering what difference this makes for someone who wants to get into coaching. I helping coach youngsters at my local club but eventually I want to coach older players, so which way is best for a coach who wants to be an “all rounder”?"

I have a confession. I hated bowling machines as a player. I wasn't alone. Yet others loved the same thing. It really is the Marmite of cricket practice.

I found it really difficult to get the timings of my movements right and often found myself rushed and off balance at point of contact. It became very frustrating when others were enjoying every bowling machine session.

Let's talk about "old school" coaching.

What's that?

It's high on my mind recently because of the appointment of Darren Lehmann to the Australian coach position. He has been sold in the media as the "non nonsense, straight talking" option. He's not about powerpoint presentations, an injury potential matrix or any other modern coaching term. In other words, he is old school.

A lot of people are screaming in celebration that common sense has returned to coaching.

Me, I'm not so sure.

As part of my course, I ask readers to send in their questions. Here is one problem I got from Ihsaan that many other bowlers experience:

In a low scoring one day game, India's stand-in captain Virat Kohli, was unusually aggressive with his field settings. Is this a method you should copy?

There are certainly times when a bit of creative thinking results in unexpected fields, and results that hail you as a brilliant tactical leader.

But you need to be careful as a captain or bowler.
