And it is injury, to Richard Kahui, which has given Guildford his lifeline.
Unceremoniously dropped from the All Blacks in 2010, disrupting the World Cup with an apology for behaviour during last year's Tri-Nations, then being suspended for off-season craziness in Rarotonga - it's been a tough road for a young man of 23.
We know of all his challenges, including the premature passing of his father, Rob - a hammer blow with surely unseen affects.
While some, including in the media, love nothing more than to kick a man when he is down, many in this province remain supportive.
It's now up to him to prove he is worthy of that support, because like it or not, with high profile comes scrutiny.
The signs however are good.
The Magpies star winger had to be considered unlucky to miss out on the initial 35-man training squad after a strong season of Super Rugby.
He showed on Saturday night that he hadn't spent the week sulking, turning in a superb one-try performance for the dominant Crusaders as they crushed the woeful Blues.
Now he must bring his A-game to the All Blacks if given the chance, and give 110 per cent off the field. We know he has the talent, it's professionalism, day in and day out, which has to become evident.
To quote Brad Thorn yesterday morning: "It's not so much about what's going to happen next. It's just about enjoying today and only the Lord knows what will happen in the future. We shall see how it works out."
Let's hope in Zac's case, it's for the best.
