It "looks" like giving too much solely based on the fact that we love to dream that Big Mac will become a great player. But honnestly, in reality, it isn't such a crazy package, while I don't say I would do it.
If Big Mac becomes a third liner and Drouin develops well, then you should go with Drouin.
The pick, well we don't know the rank of it, so it's tough to say, but drafts are crapshoots.
Beaulieu? Again, we love to dream about his potential, while in reality, it is still up in the air if he will be anything else than a Mathieu Dandenault or a Patrice Brisebois. After all, he has yet to reach the 20 points mark and is certainly not a god defensively nor an example of consistency of dedication.
A young and supremely skilled 20 years old who's available, it doesn't happen often. So yeah, we should objectively think of what Big Mac and Beau will REALLY become (instead of dreaming) before stating that package is ridiculous.
Now it's true we should do the same exercise regarding Drouin.
