If Cooper in future games beyond RWC can prove he deserves to start at 10 and can be consistent and form warrants it - I am all for starting Cooper.
But he simply has not sold any case for him starting at this point in recent performances, so until he shows in at least one game a very good game at 10 I struggle to see why so many people want to discuss how brilliant he is. Lets wait until he plays the game that proves it and lets stop raising how Cooper does this or that whilst RWC is on as who cares at this point as we are not about to start Cooper for any of the remaining RWC matches which is focus of this thread re: RWC semi final game.
I wasn't going to buy into this debate, but now feel I must offer some observations as a non-Tahs and non-Reds supporter but as a Wallabies supporter.
Very few, if any, of the posts criticising Foley's efforts against Scotland are advocating replacing him with Cooper at this time. What they are complaining about is, in their collective opinion, the different treatment they perceive Foley gets on this site for errors that if they were made by Cooper would be much more severely criticised.
The majority of responses to those posts are interpreting those criticisms to mean that Cooper should be starting in place of Foley. I do not believe that to be the case. I think most, or nearly all, posters now accept that Foley is the No 10 for the remainder of the RWC and barring injury Cooper will not get a start at all at No 10 and maybe won't get any game time at all in the remaining games.
In short, it's not the comparative skills of the two players that is the issue, but the comparative treatment of any criticism of their respective games.
Time to put it all to bed. Foley will start in the SF and the Final if we make it, and he will have a big bearing on the outcomes of those games depending on whether he has a good or bad game. Cooper's form will not have any bearing, or at best a very small bearing, on the outcomes of those games.
