Robbery -- Attribution

You need attribution in just about every paragraph. But you only need ONE attribution in a graf where there is just a single source of attribution. So you don't need this:

Tim Izzy said Omar is the stupidest teacher he's ever has in 11 years as an undergraduate student at Michigan State University. Izzy is still 101 credits shy of graduating, Izzy said.

You can take out one of the he saids, like this:

Tim Izzy said Omar is the stupidest teacher he's ever has in 11 years as an undergraduate student at Michigan State University. Izzy is still 101 credits shy of graduating.

Period.
