I am sticking my neck out and making a bold statement that the Decision review system is a disaster. It is a serious threat to fair test cricket. It is, and I dare say, cricket fraternity’s blind faith on an untested and unproven vaccine to poor umpiring. At this point in time, I would put greater trust on the worst financial risk model in the market. As an analyst, I am well aware that all predictive models are as good as their identification and treatment of sources of uncertainty. To somehow imagine that this model takes into account factors including but not limited to bounce, speed, weather conditions, soil conditions, moisture etc. and predict vertical and horizontal outcomes of a ball bowled without some degree of certainty is very difficult for me to say the least. The horrendous decision to overturn and fabulous call by Billy Doctrove against Marcus North at the current Sydney test is a case in point. The fact that the Aussies are playing like school kids despite that is besides the fact.
I welcome discussions on this topic. In particular, comments by anyone who has a detailed understanding of the DRS model would be appreciated. I hold my views until I have been convinced that the model is trustworthy. The analyst and doubter in me casts serious doubts on the credibility and, more importantly, the motive behind the use of this system. I would also be interested in finding out more on the creators, their relationships with certain cricket boards/tv channels etc. and their commercial interests.
