Williams, who has played 73 times for the All Blacks and has 88 Super Rugby caps, was a part of the Crusaders title-winning team of 2008 so he knows his way around both of New Zealand's most successful franchises.
He also knows the margins between winning and losing are often very small - the Blues lost their opener against the Crusaders by one point after Piri Weepu's late drop goal attempt was charged down and Todd Blackadder's men have lost their matches by fewer than five points.
"You don't have to win every game, you just have to hang in there consistently. Trust me, we're going to be there at the end and so will the Crusaders.''
Even so, Williams concedes winning is a habit which is why the Blues getting off the mark with a victory over the Bulls in Pretoria was so important. It also eased the considerable pressure beginning to mount against coach Pat Lam. "It was a building plank,'' he said. "We have to back it up this week [against the Stormers in Cape Town. Newlands is one of the homes of rugby so it will be another difficult one but we're up for it.''
Williams himself has had a quiet start to the season. The Blues lineout has been dysfunctional and the absence due to a neck injury of All Black leaper Anthony Boric is unlikely to help things, so the heat will be on Williams and hooker Keven Mealamu to counter the Stormers' favoured lineout drive game plan.
This was one area where the otherwise disappointing Bulls had ascendancy last weekend.
"I think I'm building,'' Williams said. "I definitely think I'm getting better.''
