Wood's major issue was he would often run on body language alone, it was an instinctive habit he struggled to overcome - he was just as bad in Shield cricket apparently.
If any Batsmen played a front foot cover/mid-on drive or even a cut shot shot and then happen to take another half step forward, the said batsmen calling 'WAIT' or 'YES' was mainly irrelevant because Wood was already on his bike and run halfway there...!
My Dad picked this up pretty early in his career and said; look, look, if a batsmen plays something off his back foot, that idiot Wood barely moves at the bowlers end....
It was just a bad when he was batting, because again, if the non-striker walked towards him and Wood thought he wanted a run, he'd just take off....
