I got a kick out of this piece from my Sports Law text:
"In sports employment contracts, another unique feature is the concept of "juice." Juice is the ability to write your own ticket based on unique skills or rampant popularity. The more juice a player possesses, the greater [his or her] ability to modify [his or her] employment contract...."
I dig that the authors put that in the book. That's the kind of lingo I wish all my texts included.
But: living in the Bay Area (home to Barry Bonds, of course), I can be forgiven for thinking the authors were going to define the term a bit differently!
