"We're a bit biased, but he's been great for us, playing long minutes, gets through a ton of work, a very accomplished scrummager, gets through his core roles, and good with the young guys off the field. If anything goes wrong (at the RWC), let's hope he gets the call-up," said Umaga.
Flanker Dan Hyatt won't be suiting up on Friday night, his nerve issues in his back seeing him leave the field and spend Saturday night in hospital for pain relief. Vaipulu, who had a shoulder problem, just had to get through the next few trainings to be right for Waikato, as did captain Tupou, who copped a knock to his knee, left the field, but returned to the fray late in the Tasman clash.
Umaga was already on the record as saying that the win over the Makos was the Steelers' best display of the season, though fans will be lamenting that they haven't seen a lot more of this confident rugby, with the semifinals now a long shot, nine points adrift of fourth-placed Taranaki.
"It's good to see it coming to fruition on the field and the boys being confident enough to throw passes and taking opportunities where we can," said Umaga, though wary of Waikato's multiple threats.
"They have some blistering backs that will make you pay for mistakes if we aren't on our game."
