Answer seems to be no based on their records this season.
Established starters:
Aden Flint now at Stoke with 5 appearances (no goals).
Will Vaulks now at Sheff Weds with 6 appearances (no goals).
Marlon Pack now at Portsmouth with 6 appearances (no goals).
Sam Bowen now at Newport with 5 appearances (no goals).
Getting game time but struggling to establish themselves:
Ciaron Brown now at Oxford with 4 appearances but only 2 starts (no goals).
James Collins now at Derby with 2 appearances (no goals).
Josh Murphy now at Oxford with 2 appearances but only 1 start (no goals).
Getting no action:
Alex Smithies now appears to be third choice at Leicester.
Leandro Bacuna still without a club
Isaac Vassell still without a club
Nothing here to suggest we should have kept them although a case could probably be made for Flint.
