The magnitude of the number may be misleading, but the fact that he tied for the worst +/- on his team isn't. Hard enough worker, but relying on perimeter play (particularly with the man advantage) to be offensively productive in junior has its symptoms/by-products and that's one of them. Not that he's the "worst" defensively on the team (they wouldn't use him on the PK if that was truly the case, though it's his speed that makes him at least half useful out there), but if the puck isn't on his stick he typically isn't doing much toward the team cause.
He got a ridiculous amount of ice and always faced the other teams best players. As we say in French, one plus one make two. Play a lot, on a terrible team, and see what happens.
He played over 25 minutes of ice, on one of the worse team of the league (I still believe Saint-John and Shawinigan were lesser teams).
Look at this, only Jérémy Roy and Dominic Talbot-Tassi played more than him, and both are defensemen.

He has work to do in his own zone, but +/- is probably the worst stat used to analyze hockey. It tells you who was on the ice, but doesn't tell you if it was a certain player's fault, if it was a brutal turnover from a defender or just a weak goal allowed by the goaltender.
You're right to say that he's at his best with the puck on his stick, but his problem defensively to me is not necessarily in terms of position or coverage, but rather his puck decisions. He makes too many turnovers in dangerous areas of the ice (the two blue-lines notably). He's very confident in his abilities and always has his mind on 'Offense'. That's something he'll have to improve, play accordingly to the clock and accordingly to his position on the ice.
I'm confident that as he matures he'll get better at understanding when and where it's time to deke through a defender and when it's time to put the puck deep.
No matter how small you are, you still need to show you can play through traffic and won't always be on your ass with a significant lower body strength. Audette has some ways to go. But I would indeed love him on a much better team.
I expect Sherbrooke to end in the 8-12 area in the standings and they should be amongst the contender in 2015-2016. Daniel will again get a lot of ice and he will play with the best Defenseman of the league in Jérémy Roy. The Phoenix traded for David Storto who was a linemate of Audette's at Esther-Blondin in MAAA. That will finally give him options other than creating plays by himself.
Here's what the team looks like right now. We have a top3 D squad with Roy, Bahl, Neill, Hoyles and Grégoire. Goaltending is average but is an improvement on last year. And offense is definitely better than last year. Wieser will be older and should be good for a PPG. They'll pick up a 17/18 year old Euro at the draft. They finally have a decent checking line with Lafontaine and O'Brien and the Debiens/Harwell/Deslauriers line showed promise at the end of last year and should explode offensively, especially Harwell and Deslauriers.
