Without even reading between the lines it appears that CPR's comments clearly indicate Jantz won the competition outright and Tiller was not in the picture for the future.
CPR - "Rhoads expects Tiller to remain with the team and left open the possibility that Tiller could change positions in the future."
You wouldn't mention a position change if Tiller was in the QB picture.
