So easy for you to say from the luxury of your computer, without an iota of what it takes to be an NHL GM nor having absolutely any clue of what actually happens when it comes to being a GM. It's like you telling a homicide detective (assuming you aren't) how to their job IN HINDSIGHT. But of course you are so smart this doesn't apply to you, right?
Anyways, Gillis tried to be patient with Luongo for whatever reasons and it didn't work out the way some CDC'rs demand it should. Get over it.
