All indications are that Tameifuna could fall into the second category.
Certainly his employers, the Chiefs Super Rugby franchise, seem to be doing everything in their power to ensure he has the necessary support to get through this problem.
Tameifuna was supported in court by his mother and Chiefs assistant coach Tom Coventry, who had also written a letter to Judge Richard Watson outlining an "eight-point plan" to help Tameifuna.
Coventry seems like the right person to help Tameifuna - he has known the burly prop since he was a fifth-former at Hastings Boys' High School and hosted Tameifuna at his Hamilton home during this year's Super campaign. The plan includes placing him in a stable flat close to training, access to a full-time trainer, medical staff, and a personal development manager to help him with his community work. He would also receive peer mentoring from senior players.
The judge acknowledged the plan and as a result gave him community service. There will be some people who will say that Tameifuna got off lightly, but they would be wrong.
His crime is relatively minor in the grand scheme of things. He was not driving recklessly or drunk and any harsher punishment would have been detrimental to his future.
This may just be the thing that puts him back on the path to greatness.
And if he barges over from five metres to score the winning try for the All Blacks in the next Rugby World Cup final, we can thank the Chiefs and the judge for making the right decision.
