I'm sorry, but what? Not what I said, at all. Let's walk through this.
Willis' rookie contract was set to expire after 2011.
In May 2010, Willis signed a 5-year $50 million dollar extension covering the years 2012-2016. That's $10 million dollars a year for those 5 years.
At that point, his entire contract, covering 2010-2016 (7 years) was worth around $53 million, because his rookie contract wasn't that pricy.
Oh, and the extension came with $29 million guaranteed.
Lee signed a 6-year extension, if I understand this right, that will cover the years 2014-2019 (he's in the last year of his rookie contract). That extension is worth $7M (and possibly up to $8.5M) per year, much less than what Willis got. Also, it includes only $16 million guaranteed, much less than Willis got.
Sean Lee is not making Patrick Willis money. At all.
