Not really sure why "was a physics graduate student" means anything about his business acumen here. Eric Lefkofsky has a law degree, Brad Keywell has a JD and an MBA, we could do this all day. Having a graduate degree in a hard science could certainly suggest a person has a different way of approaching business, but Wang dropped out so he could unapologetically clone other people's ideas.

I think the OP is stating the opposite, that being a physics grad student would imply he probably couldn't run the business as well as the Groupon founders.

However, in the same sentence he's described as 'very competent'.

Ah, well then I'm a doofus. That makes sense. Apologies, OP.
