Adding Athletes as Characters, Teams as Concepts

What are the rules (if any) in regards to athletes being added as a video game character, or sports teams being added as video game concepts?

My point of view: adding cover athletes (such as Vince Carter), players to have a series of sports games named after them (such as Ken Griffey Jr. and Wayne Gretzky), or specific characters that are unique to the series or are in only a select few of the sports games out there (like Barry Bonds' replacement in MVP Baseball 2005) are fine. Nobody else.

Pages in question: Marc-Andre Fleury, Pittsburgh Steelers

You should read my topic on this. Here.

I was thinking about this too.
