The bottom line is, we need to address the supply, the chances created for our strikers. We could sign anyone, but if there's no supply, no someone creating from midfield we are unlikely to score bucket loads. The problem lies in the lack of creativity behind the strikers, rather than with Yates, Madine, Beesley or Lavery.
I'm not sure that the constant rotation helps the strikers at all, Critch needs to decide on his best front two and play them, barring injury. Jerry Yates could be one of those, but he needs to play, regularly.
