Basics of editing: Forbidden verbs
Here's the basic cutline rule again: Don't tell me what I'm seeing. Tell me why I'm seeing it. Follow that rule and you'll never be tempted to write "celebrates" when you can write about what's being celebrated. If the touchdown was, as the game story contends, the most significant play of the first half, borrow that description: "Michigan's Devin Furness took a pass that appeared headed for a Penn State defender and walked it in for a 43-yard touchdown in the first quarter."
As for "shares a laugh with," just don't.
