For me, Sharp looks like he doesn't quite have the confidence yet. I don't know if he was the pre-game allocated pen taker, but if not, he probably wanted to get back on the scoresheet and show that he can do the duty when Rickie isn't playing. Tough when you know Rickie hasn't missed a pen for us, and consequently Saints haven't failed to score a pen all season (correct me if I'm wrong on that point, but can't remember one). All the more reason for him not taking the pen, but then again, all the more reason to take it.
I'm thinking more medium-term - if we do go up this season, regardless of today, do you think he's Premiership material - or likely to be a squad player for us?
Remember he is still not going to be himself, after moving down, and all the tough times he's been through.
