I think so - Oosthuizen and JCW are penalty magnets at scrum time,
I'm not sure what injury JCW is out with, as well, but he's been out for almost 6 months now - who knows what longer implications that will have on his career?
They also both have 1yr left on their contracts and I'm not sure either will be around longer than that
Easier to sign one 3 this year and one next (with Harper taking the 3rd slot) than scrabble around trying to sign two prem standard tightheads at once next year
Harper showed potential in his cameo the other week, but I don't want to rush his development too much, especially as he only recently converted from the backrow
