Well, as mch as it pains me to say this, the Stormers have a long and (not so very) proud history of playing dead against SA opposition in the last round of league play, especially if said SA team is in a position to make the semi`s.
Last year they lost 43-10 to the Bulls, who needed 5 points and a points difference of +33 to go through. Contracts all round were suspected by the Sharks players, who missed out. In exactly similar circumstances, the Stormers gave up a 75-14 result in the final round to the Bulls the previous year.
I really don`t think that the Stormers can turn it around in this game- the Sharks have been simply massive up front, their young centres have cooked in the backline, and youngsters like Sharks twin Ndungane, JP Pietersen and Frans Steyn have all had moments of attacking brilliance in the latter stages.
Sharks to take it, with a bonus point, and, if the Crusaders gets only 4 points in their final game, by a sufficient margin to end top of the log on points difference( would have to be a repeat of 75-14).
