I was thinking about this too. When I'm in the nets I seem to have way more time to play shots and can manage to choose my foot selection a lot better even against the fast bowling. But I think it might just be that in the nets I'm more relaxed. I don't know about you guys but I get really tense sometimes when I'm playing in actual matches, especially as my career player, and I find that when I can manage to calm myself down a bit (breathe!) I play better.
This is one of the things I love about batting in this game, it's really managed to simulate the mental side of batting which is so important. On cricket games of old when you were told where the ball was going to pitch 5 minutes before it's bowled there was nothing like this for me. You really need to have a clear head to bat well, just like in real life. I find that often when I get out it's because I've started thinking about what shot I should play, like if the dots are starting to build up and I feel I need to attack more, or when I try to premeditate what they are going to bowl, like when they've bowled say 4 or 5 deliveries on off stump and I start thinking, 'Jeez, they cant be this accurate, surely this next ball will be short or going down leg...' and then before I know it, bang, plumb in front trying to play across my pads, Shane Watson style! Haha
