To be fair, I wouldn't be surprised if another striker does come in, though I suspect that the fact that Ince and Snodgrass can both play a second striker role may reduce the chances unless a really good deal comes our way.
Long and Jelavic were also a lot more prolific for us than they seemed after joining us. They didn't seem to score very often, but a big part of that was that they were ineligible to play in the cup games which obviously meant longer between goals. Their strike rates would give us 25 goals between them over a season, and when I did the comparison at the back end of the season there weren't many teams in the league that got more than that from their top 2 scorers.
