You're missing the point. We don't necessarily need a goalscorer, though that would be ideal. We need a fresh pair of legs who can occupy and keep central defenders honest - whether that's in the air or as RH prefers in behind them. Long has showed he can do a job of sorts in that role and he's not a goalscorer. The problem is that we don't really have an alternative once we sub the main striker. We've tried Sims, Obafemi, Austin, Redmond and Gallagher who've either come up short, got injured or are not suited to the role. When Ings is healthy, we can bring on Long; but that's not something we've been able to count on -and even if we could count on Ings, frankly we can improve on Long.
