Where are you getting this??!! What is the $1.267 average for offensive linemen?? You can't take the average for offensive lineman and figure doubling that is the contract Nicks will get. That is counting alot of minimum salary guys that are on rosters for depth. If you want a true value or rather projected cost of a player, you need to look at comparable recent contracts....you will quickly find Nicks is going to make alot more than $3 million!!
2012 NFL Top Average Salaries - Guard
Now, if the signing bonus (and some roster bonuses) are high enough, Nicks may agree to a couple of base salaries of $3 million, but I would think he and his agent at a minimum are looking to be in the top 10 paid guards in the NFL...and if the market is right, I would say top 5 is a real possibility.
