It has arguably been something that has hampered them in their pursuit of not just a play-off spot but the Premier League.
And it is depth in the striking department, or a lack of it.
With Albion heading into their fifth straight Championship campaign - they have Aune Heggebo, the new £4.7m who looks likely to lead the line.
He is leading the line as he comes in as a big money signing and is obviously rated by boss Ryan Mason.
But you could argue he's also leading the line because Albion have, yet again, suffered injuries in the striking department.
