Are Kitshof and Kock forcing themselves into the test side?

Yes without doubt. Kitshoff should have had a test cap ages ago.
Meyer needs to wake up to the talents of these youngsters plus the likes of Willemse, Jacques du Plessis, Thomas du Toit etc

 Thomas may not going to be ready for world cup. Still too young.
Kebble, Kitshof, Kock and Malherbe will be in contention. I like the look of Kebble.
Meyer is now in an awkward position with his older player fading and young guns no test experience. Shows poor planning.

Thomas was owned by the Stormers 

 You dont comment onKithof and Koch Moz?I would liek to see them take on Beast and Jannie. I suspect they will prove  to be better. Meyer needs to see this

 Beeno
After watching the Cheetahs - Sharks game I realize how pathetic a combination of props of Jannie and Beast has really become.   Oosthuizen was by a mile the ebst prop on the field in that game.
Lets face facts Jannie is not up to standard anymore and Beast has also become a serious problem.
I would say there are at this stage four tightheads better than Jannie.  Coenie,, Koch, Malherbe and Marcel van der Merwe.
There are also Kitshof, Trevor Nyakane, Schalk van der Merwe and Oli Kebble are better and stronger scrummaging props than Beast.
As you  said the deterioration of performances of Jannie and Beast and the retirement of his pal Gurthro has put Meyer in a spot.   He will obviously persist with Beast and Jannie - which will be another nail in his coffin as a coach.
Poor Mozart - he must be i n absolute agony about his "national treasure".
