How many receivers could we take with our first four picks before you would be upset?

I was looking at a mock that had us taking DGB in the first. I love the pick. If were going to gamble on a receiver might as well go all in on the gamble. It got me thinking with receivers like Greene, Lockett, USC guy, Dorsett, Montgomery still on the board how many is too many to take in our first 4 picks?

DGB, Greene, OG, and Lockett/Dorsett/Montgomery with our comp pick would absolutely be fine with me.

What is your take?
