Not questioning your source, but this argument seems pretty weak. Aren't these professional football teams? I am sure they are going to be prepared for any of the 3, regardless. To use this as an excuse to play EJ first seems juvenile and should really put Rex in a bad light as far as I am concerned.
Also, the trade value argument goes directly against Rex's claim they will probably keep all 3.
For sanity sake I hope Metz source isn't with him
