I say keep all the young guys in the team, including Crozier. They need more games with the big boys. When they get injured, or suffer form slumps, then you've got a pool of solid players at Peel to choose from.
OK, maybe bring Ibbo back, and you can drop Zac D, but we won't learn anything by bringing Suban, Clancee, De Boer or Mzungu back.
