Well, maybe it's to early to say for now but it's a positive sign from the fast bowler and now he's not just playing test's for england he's also playing ODI's which I never seen coming. I thought since that dismal 1st over in the Champions Trophy against India that was his ODI career over but you cant keep a good man down for ever.... although it was a couple or even a few years he's back and thats the main thing playing 50 over cricket which in the test's and ODI's against South Africa he's played very well and most importantly controling his emotions and his line and length. So hopefully for the future he can stick in the side and be a great bowling asset for England in the future years and not let his nerves get the better of him.
