Officially it's Reick. At least according to his best times at training. If he was still in first grade, it would be Joven Clarke.
But you've got to wonder what good it is having a great time at training if you can't pull it out come game day. Some examples- last year, Justin Murphy scored a 90 metre try, running straight past Rieck who couldn't make up any ground on him. What about Ryan Cross?? Apparently he is one of the fastest in the comp, but when he made an intercept against Newcastle last weekend he got run down. Ditto Elford from the Tigers, he has great times as well, but when he made an intercept against the Warriors they were coming from all angles to run him down, and the Warriors don't have any noted speedsters.
Matt Cooper is another one of the fastest, has a time of 10.7 over the 100m as well.
