Blair accidentally bumped into the referee in the in-goal area before continuing closer to the sticks, and there was a suggestion the conversion may have been taken in line with where that contact was made instead of where the ball was finally grounded. However, it's highly unlikely that was the case.
Fortunately, Smith potted a penalty goal soon after to extend the lead to eight, which was just enough of a buffer after Aidan Sezer converted Elliott Whitehead's try with just a few minutes remaining, reducing the final winning margin to two.
Had Melbourne not scored four points from penalty goals and Smith's missed conversion from out wide cost them the game, questions would no doubt have been asked about why he kicked from the difficult position he did.
But in the end it didn't matter as Melbourne ended the Raiders' dream run in 2016.
The men in purple will play Cronulla - who have never won a premiership - in next Sunday's Grand Final. The Sharks will be the overwhelming crowd favourites, but that doesn't faze Smith.
"I don't think we've played a final in Sydney when anyone's been going for us," Smith said. "That's sport and that's part of the game and we've done it all year.
"We've played 13 games away this year and we haven't had too many people there supporting us but I'm sure we'll have some purple in the crowd.
"At the end of the day, the crowd isn't going to have an influence on the game, for us it's there to be won and we can control what we do."
Melbourne coach Craig Bellamy watched the Sharks roll North Queensland 32-20 to win through to the big dance, taking note of playmaker James Maloney, who scored two tries and kicked six from seven goals.
But Bellamy said he wouldn't take too much from the Sharks' performance against the Cowboys, preferring to concentrate on their own meeting in Round 26 when the Storm beat Cronulla to win the minor premiership.
"We played them only a couple of weeks ago, so we will probably go back to what we saw there, and our games before that, as far as what we're going to go with for a game plan," Bellamy said.
"You know they've got real quality halves - Jim Maloney was outstanding - and they've got a tough pack of forwards and some really quick, strong outside backs, so they've got a really good balance."
