If Rein is picked at 9, there must be a replacement on the bench, either Hinchcliffe or Peats. He is a gun defender, but his small stature ensures he always gets targeted. Usually for Saints he plays ~30 minutes, gets replaced by L'Estrange, gets a 20-25 minute rest plus the half time break, and comes back for the last 20-25 minutes (Sunday was an exception where he played the first 60 and then went off). This is a big part of his improved form, although he has obviously also worked on his passing, decision making, and kicking game, which were all terrible the last couple of years.
