From an article dated August 20th of 2011 that I looked up for info on Kalil's contract (link)
The Carolina Panthers continued their surprising spending spree Friday when they signed center Ryan Kalil to a six-year contract worth $49 million that will make him the highest-paid center in the NFL, according to team and league sources.
The Panthers transactions since the NFL lockout include re-signing its own pending free agents such as defensive end Charles Johnson (six-years, $72 million), running back DeAngelo Williams (five years, $43 million), linebackers Jon Beason (five years, $51.6 million), James Anderson (five years, $22 million) and Thomas Davis (five years, $12 million).
The Panthers also signed kicker Olindo Mare to a four-year, $12-million contract...
That wasn't the last of it, of course, but that was what they had done to date
The article also includes this line...
After a flurry of free agent and trade activity that surprised many around the league, Panthers general manager Marty Hurney had identified Kalil's long-term deal as his next priroity.
Apparently both Yasinskas and his ESPN editors missed "priroity".
But typos aside, take a look at those contracts, all signed in relatively short order.
