4. Alex Mack
During free agency, the Jaguars tried to lure Mack out of Cleveland with a five-year, $42-million contract; but the Browns knew that they couldn’t let their center get away, as they quickly matched the offer and made Mack one of the highest-paid centers in the league. Why is he worth that kind of dough? Because he’s consistently good. During his five NFL seasons, Mack has never missed a game, playing at a Pro Bowl level throughout his career.
3. Logan Mankins
At the end of the 2014 season, Mankins will have completed a full decade in a Patriots uniform, becoming as synonymous with New England’s run of success as any player not named Tom Brady. And for good reason, as the left guard has earned a trip to the Pro Bowl following each of the past five seasons, a testament to the fact that he’s always the consistently good element in the trenches for Bill Belichick and Company.
