Mike Leach’s innovations changed football forever and helped the sport enter the 21st century

Many college football luminaries, including Lincoln Riley, mourned the death of Mike Leach, whose central legacy is his influence on the evolution of offense in the sport.

On Tuesday morning, Mississippi State head coach Mike Leach passed away at the age of 61.

Leach was a beloved head coach, and one of the most unique personalities college football has ever seen, in this or any other era of the sport’s 153-year history.

Leach’s coaching tree was long and influential. Lincoln Riley — the current USC Trojans head coach — credits a ton of his success to Leach.

After the unfortunate news hit the wires and the headlines, Riley, Alex Grinch, Gus Malzahn, and many other prominent figures in college football came to show their support for Mike Leach.
