Three incredible stats show Mack's immediate impact on 49ers


Last season the 49ers' offensive line struggled to contain pressure up the middle. After signing center Alex Mack this offseason, the problem has been solved. 

Having played under Kyle Shanahan for two (2014, 2016) of his 13 NFL seasons, Mack played a key role in the offensive success of the 2016 Atlanta Falcons. 

In desperate need of a center to plug the middle of the offensive line, a reunion with Mack was a match made in heaven for yet another Shanahan offense. 

Through two games this season, the 35-year old center has been phenomenal. 

Having been sacked just once this season, quarterback Jimmy Garoppolo can thank his center -- and the rest of his offensive line -- for the stellar protection upfront.

Not only has Mack been dominant up the middle, but he's done so without committing any penalties. 

A clean, consistent brand of football is why Mack continues to be one of the best options at center in any Shanahan-led offense.
