One recent example of this is the contract signed by Derek Cameron Wake. It was widely reported in January he signed a four-year deal that could be worth $4.9 million. Nope.
Wake's salary is scheduled at $310,000 in 2009, $395,000 in 2010, $480,000 in 2011 and $565,000 in 2012. That adds up to $1.75 million. He got approximately $1 million in bonuses and guarantees which bring the deal to about $2.7 million and he has another $900,000 or so in incentives that bring the potential total of the deal to about $3.6 million.
