He has the talent. But like most have said, he needs to cut out the mistakes and penalties from his game, or at least minimize them.
Personally, I wouldn't mind seeing Des starting Keppie over Taupau. I think a front row of Paseka and Keppie can be a very strong one with Taupau coming off the bench with either Sips, Boyle, Aloiai or Bullemor being the other prop.
Yes I agree 100% that our starting props should be Keppie and Paseka, with Taupau and Aloiai coming off the bench. Our first round seventeen (barring injury) will have either Lawton or Bullemore at twelve, and the other on the bench. When Schuster is fully fit I have Bullemore, Walker, Aloiai and Taupau as the bench players, and Lawton dropping off.
