mckenzie for burton (if injured) could easily work.McKenzie only comes in to replace Jonas or Clurey. A swap for Hammer makes no sense and throws our balance out.
None of Fredrick, Woodcock, Mayes, Drew and now Hammer command a place on talent or balance/structure and are interchangeable.
Calling drew out after he lodged a 32d 1 goal 5 clearances game is a bit funny.
