Neither of them ! A good well structured S/C team should have had either, Dwyer, Mayes Macaffer or Jake Stringer as bench players .
Both players are pretty much "On and Off" the field. But if you really need to decide on which player to keep, i suggest you keep Ricky Petterd. He'l lift at the Tigers.
Crozier. None of them should be in your team.
