Archer has a loose-limbed approach in a run-up that is not very long. He gets into a good position at the crease and releases the ball late from a very high action. He snaps the ball down at genuine pace. He has rhythm to his bowling.
Roland-Jones is a good, old-fashioned English seamer. He's not especially quick, but he pitches the ball up and swings it away, which is always dangerous.
What we have learned is that Roland-Jones is a very promising prospect. Because of the way he bowls, he will not blow batsmen away, but is more likely to take wickets through accuracy and building pressure.
On your debut, you just want to get into the game. I remember when I played my first Test, we bowled first and I went wicketless in the first innings. I felt like I was searching to make a contribution.
Stuart Broad's 400th Test wicket did not come the way he would have wanted - Tom Latham chipped the ball to mid-wicket - but he will take it nonetheless. It is a fantastic achievement.
The absolute key difference between television and radio is the ability of radio to communicate. With television you can watch the screen and your mind can be anywhere. On radio it requires a certain amount of discipline from the listener to follow what's being said.
It's an interesting education to listen to cricket commentary when you're not at the game. When you're there, which is most of the time for me, it flows over you. But when you're not there, you look at it in a slightly different way. You pick up things.
The bouncer shouldn't be banned. Hitting batsmen, I'm afraid, is part of the game. But it's the histrionics, the nonsense, the prancing, the in-your-face nastiness. It's become accepted, and actually it's not acceptable at all.
I look at some young commentators who sit down with piles of notes, and of course, what are you going to do if you've spent hours preparing all this stuff? You're going to bloody well read it out. Boring!
Adelaide is terribly underrated. There are lovely wide streets, beautiful parks, one of the most scenic cricket grounds, wonderful beaches, and vineyards nearby. The food and the people are lovely, and it's not too big and sprawling.
I played at school then signed up with Leicestershire when I was 18, for £20 per week. In those days cricket wasn't a full-time job; in the winter you had nothing to do.
Divorce is something I think that children feel particularly hard and what's sad about a lot of divorces, and certainly about my divorce, is that absent fathers who really want to play a part in their children's lives but don't live there, they have a pretty tough time.
Rather than influence the media, I hope that my progress from player to correspondent shows that there is a role for former cricketers in the media, despite the intolerant views of some of my colleagues in the press box.
I wish I'd done better for England. I only played three Tests and three One Day internationals. You have to take your chances and, for whatever reason, I didn't.
When you know that batting will be tough, that the ball might move around and your technique will be tested, you have to make sure that you don't give the bowlers any more advantages.
