Walcott was a pretty good keeper while he kept, and I would have him over Flower and Knott both.If the team is that weak just play Flower as a batsman and let the real keeper hold the gloves.
From everything I've seen and read I would even rate Walcott over someone like Flower, and easily at that.
Here, we are going of the basis that you can only have one: Knott or Flower, and whoever plays keeps.
