I'm not suggesting Symonds can't bowl but let me put it this way, would he make any side if he relied on his bowling alone?
He bowls medium pace and off spin but both types of his deliveries are similar, nothing special, eg bounce, swing, spin,etc but just decent line and length, however the point I made about Watson is that he'd probably get into a few sides with his bowling alone, his 1st class bowling average is 25, he opened the bowling for tassie the other day, Ponting was using him as a genuine part of the bowling attack before his injury, note the england game where he dismissed both Stewart and Hussain towards the end in last year's VB series, and as evident on the weekend he seems to get good swing as well.
