I think by Florida sending him down despite how well he has played it is a clear message that they want to give him more time to develop in the AHL this year. Barring an injury or trade he will not be back up for any significant time this year. In a limited keeper such as your pool is I see little reason in holding on to him despite his huge future talent, as he would not be your goalie keeper over Lundy. So I would drop him. If he get's called back up you can always snag him again...
