Manziel led Texas A&M to a 29-24 victory over No. 1 Alabama in November 2012. That season Manziel won the Heisman Trophy, which is awarded to the most "outstanding college football player" each season.
In that game, Manziel completed 24 of 31 passes for 252 yards and two touchdowns, and ran for 92 yards on 18 carries.
"You absolutely give respect where it's due," Manziel said this week, "and they're a program that has won numerous national championships and been at the top of the SEC.
"You respect them, but you don't fear them."
"Turnovers is the easier answer to give," Manziel said when asked for the key, "but what's important is to be extremely efficient and take care of the little things. Don't make things any worse than it already is being out there against a defense that's extremely good and fast. Take what's given to you and live to fight another day.
In the last six years, Alabama has lost just eight times.
