Browns C Alex Mack's 2013 salary increased from $1.332 million to $3.732 million after he hit escalators in his rookie deal.
Mack has been the picture of consistency since entering the league as the No. 21 overall pick in 2009. He's never missed a start in 64 games. Mack graded out as Pro Football Focus' No. 9 center in 2012, a year after checking in at the No. 10 spot. He's a candidate for a contract extension this offseason as he enters the final year of his deal.
