Frans vs Zeilinga

Zeilinga is a bog ordinary player. I don't rate Frans as a 10 at all but I'd take him over Fred.

 It is like comparing two B-grade flyhalfs to decide which of the two is the better player.  In the recent game when Steyn played as flyhalf he was way below par and he was severely criticized for a below-par performance.   
I will be frank - Zeilinga is a below par flyhalf preferred by White over Swiel - Steyn is no flyhalf - he does not have the ball sense to be one.   
    

But the Sharks won...as they have generally done at a far higher rate when Frans is at 10. Handsome is as handsome does, Steyn finds a way to help his team to win.

 Mozart 
How many times has that statement of yours been disproved - even you said at one stage it is unscientific - yet you keep repeating that as if it has any real basis at all.
Steyn does not have the ability to read games and take decisions benefitting his team.   Even though the Sharks beat the Force in his last game for the Sharks by 15-9 - his performance at flyhalf in that game was so poor - it kept the Force,  one of the poorest performing teams in Super 15, in contention all the time.   It was severely criticized in all the newspapers and comments generally was that he should never play at flyhalf.
Fact remains - he is no flyhalf - end of story.       

Frans has been crap at 10 for the Sharks, them winning has stuff all to do with Frans at 10
