Implied value and draws

[BZ_Zorro]

Does implied value make it ok to call a pot sized bet on a draw?

Just had a conversation with a marine who said it was...he ended up threatening to "talk to his IT buddies" and get me drafted. Neither or us is giving a quarter, so we're gonna let the experts decide. He wanted to bet me $100 that your opinion would be in favor of him, but said to forget it later on.

Two questions:
Is calling a pot sized bet with his hand a good play?
If he somehow expected me to go all in on the turn, was it a good play?
