You cant blame Rudd for the Crouch goal. 6 feet 7 striker with champions league and world cup experience, outside the 6 yard box at the near post. No keeper is coming and claiming that ball, not even Maxwell.
But, the idea is correct. By rarely coming to claim the ball Rudd makes far fewer 'howlers' than Maxwell does, however being rooted to his line there is a greater level of pressure on the defence, leading to us conceding more.
Maxwell receives heavy criticism because his mistakes are very obvious to any observer, Rudd's mistakes are, in my opinion, less visible but he makes more of them. His clean sheet record is a direct product of these mistakes
