CJ Stander is very good - I'm shocked that he is leaving the Bulls. He is only 22 - he made his Super Rugby debut this season, and has played in all the Bulls games this season I think (and started in most of them). He captained the South African under 20 team a couple of years ago, and I though he looked like he could be a future Springbok (though they do have great depth in the loose-forwards). He is a strong ball runner, capable of playing all three loose-forward positions, and seems to have a good nose for the try-line. He is a great acquisition in my opinion.
