The Rangers really in some ways were victims of their own success. They had thrown away their future for ex-Oilers (Messier, Graves, Beukeboom, Lowe, Anderson, Tikkanen) and ex Blackhawks (Noonan, Matteau) and it had worked.
There was a really really deep belief in the idea that players who had won the cup had a certain mystique. There was much more emphasis on veterans who had done it many times compared to young players.
The Rangers later sold the farm for Kurri and Mccsorley.
They were trading for Samuelsson who they felt would make them tougher on the back end, and Robitaille who they felt better fit the age profile of their core. But it seemed really stupid at the time and history bore that out.
