It'll be interesting to see who will be filling the voids left by all the players taking part in the groot trek; Kirchner, Steyn, Olivier, Kruger, Ralepelle, Vermaak and the Potgieters...
I just realised as I was typing each name that the Bulls already have many of those places covered with Serfontein, Pollard/Fouche and Botha and having now signed Van Zyl at scrummie. They do lose a lot of depth though with Olivier trekking and Venter moving to the Free State thinning the depth at center even if Serfontein and Engelbrecht are quality starters. The Potgieters they can manage without and SA has a host of quality loosies but replacing Ralepelle and Kruger (so soon after losing all of Botha, Botha, Matfield, Rossouw and Steenkamp)? Who are the likely players to step into those roles? Kirchner needs replacing as well. Even though I don't much like the guy he is a good SR player and fit the Bulls well.
