Allison scored 7 league goals in 73 games (29 starts, 44 sub). He scored 4 times in his first 7 games, and then 3 times in the remaining 66 games. He scored once in his last 53 league games.
In his final season, 2003-4, Allison featured in 39 of our 46 league games. 14 starts, 25 sub appearances.
He scored once, in the 3rd game at Palace. He failed to score in his last 36 league games. Of all our forwards, only Saint Oli McBurnie of Hull has a longer league scoring drought to his name this century (and perhaps ever).
He did score twice in the FA Cup during this span, to be fair.
As for bringing others into play, I remember his excellent performance at Gillingham when he assisted Pesc when he got his hattrick, so there was certainly some of that.
But as much as I liked Allison, and I realise it's about more than goals, I do wonder whether we would have been better off with someone who could actually score once in a while, especially as we missed the playoffs by 2 points. I certainly think this will be the case with Ayew.
