If you watch the video of the 2-2 draw at home to plucky wee Partick, he could have done better with both goals (maybe I'm being a bit harsh on the 1st one as the defence in front of him was certainly far more at fault than he was). In mitigation, the pitch was frozen solid and it was like playing on concrete. As a side note, this game was shown nationwide in the UK on ITV's Big Match as well as Scotsport, as this game and Leicester City's were the only two that survived the big freeze that weekend.
Like I said, he was a decent shot stopper (IIRC he saved a penalty at Pittodrie), but in other aspects of the game he was weak, IMO. But he was for sure entertaining and he certainly brought a bit of good ol' American razzmatazz.
