Knight's position is similar. He too was selected as an injury replacement, and isn't playing today unless another player pulls out due to injury.Menzel was nothing other than a short term replacement, he played fine in round 1 and was dropped after that. The only way he stayed in was to have played out of his skin because he wouldn't be moving upfield to replace either of Mackay or Milera when JJ returned.
The only difference Menzel was dropped when JJ and Kelly returned, while Knight was injured at the time. The end result is the same.
Today's team is our best 22, minus McGovern and (maybe) Cheney. Knight is the next small in line, followed by Menzel. After that you can throw a blanket over 3 or 4 of them.
