If Watson is in the side, Symonds's bowling will be completely and utterly irrelevant really. If Symonds gets selected ahead of Watson, I'll be angry and disappointed, but at least I can actually see the logic in it. If Symonds gets selected as well as Watson, I'll probably be less angry because Watson is there, but at the same time, more confused at annoyed at the selection of Symonds. If there's already five bowling options in the team better than Symonds, there is little to no reason to select Symonds over a better batsman for the sake of his bowling.
The selectors found a one to drop Brad Hodge the series after he scored a double century while he still averaged 58 in test cricket - I'm sure they wouldn't lose much sleep over dropping someone who averages 27 and is comparatively rubbish at test level. Without Symonds's bowling, I has doubts he EVER would have played a test match, and while he is undoubtedly a very good bordering on great ODI player, there is no way he should ever, ever be considered as a specialist batsman in test cricket. I struggle enough with the fact that he makes the side as an allrounder.
