Jewels have been hard to locate this season with the Blues.
Captain Luke Braid and sidekick loosie Jerome Kaino have glittered and there has been more of a shine about Ma Nonu's play. Too often others' form has resembled an intermittent strobe light.
One who is starting to develop the constant sort of glow coaches love is Patrick Tuipulotu, the young lock who was called into the first All Blacks training camp.
He was involved in plenty of hard yakka as the Sharks came to town, work which became even more important when his senior locking teammate Tom Donnelly went off injured.
Senior Sharks like the du Plessis brothers, Tendai Mtawarira and Willem Alberts increase their combat levels when they feel challenged or have to absorb more heat.
