Some might contend that it is unfair to say most of Manziel’s success came outside of the structure of Kevin Sumlin’s offense. In his two year career, Manziel’s two worst statistical games were both against LSU. Last year, I noticed while watching film of Barkevious Mingo that LSU employed a "mush rush" against Manziel, meaning that the line all held their respective points of attack and made Manziel pass from within the pocket.
This season LSU employed the same defensive strategy. In two games against LSU, Manziel was 45 of 97 (46%) for 500 total yards. 250 yards per game doesn’t sound terrible until you dive deeper and realize that’s 5.2 yards per attempt. The most damning statistic is his 1/5 TD to INT ratio. Manziel simply couldn’t exploit LSU’s secondary despite facing little pressure, which was by design.
