I've thought a lot about all the extra information the Broncos have.  Generally speaking - without transparency and justifiable reasons,  any choice can seem arbitrary.  Vance has said Sloter has played well and showed intelligence at the QB position.  He has also said that the depth chart hasn't changed... ?  Coaches have more information, fine - how about they share it, because based upon my information (my eyes) this situation isn't that complex
