Nothing wrong with your logic or reasoning but 9 delistees in one year after 10 changes in 2007 just seems too many.
Maybe 6 to 7 would be more like it IMO - but I'm not sure of who would make that number up apart from Jericho, Doughty and Massie.
Hentschel & Gill are both big IFs - I certainly hope that they both go on to have successful careers. If they both perform then there is no need for either of them to go.
AbsolutelyWhat further complicates it though is that we have all these known delistees in the next 2 years, without making any allowance for failures amongst those drafted in 2006 and 2007.
Gary Ayres really did bugger up the list management side of things!!
