DETROIT -

Sometimes, Calvin needs to focus on football, and only football. That's what 'Johnson' is for.

In a new Nike commercial, Calvin Johnson's alter-ego named "Johnson", played by Sean Puff Daddy, P. Diddy, (we've lost track) Diddy, takes care of the responsibilities that come with fame. Signing autographs, taking pictures and talking to the media. As the commercial's tagline explains, "Calvin has the football. Johnson has the rest."

Calvin isn't known as being an extrovert. The commercial shows the pressures of being in the spotlight, and perhaps lets us all into the mind of is, arguably, the best receiver in the NFL.
