Yeah but that's just **** bowling, not an obsession with bowling short. Tait's not exactly known for his pin-point accuracy when he has his tail up so if he's off his game, well, charitably, the batsmen will get some width to work with.
At his best, in amongst all the crap, he bowls the highest proportion of wicket-taking balls in a given over of any bowler I've certainly ever seen. Check this out, ING Cup final from a few years back;

14 wides! But 6/41 and almost bowled SA to a win in a game they had no business even making close (still
at the ball Jaques had to cope with).
