You do realise we didn't have Sharp in League 1?
And if you're not sure why people "idolise" Sharp, I'm guessing you didn't attend games while we weren't in the top flight.
He was crucial in the last half of our promotion winning season with vital goals and general all round play at that level. Scoring twice against the skates helps a lot too.
But yes, in hindsight maybe we should have signed Austin too. In fact we should have also signed every other player that ever went on to do well.
