Two
University of Michigan alumni, Lon Barringer and Rocco Gorman, recruited Renda and his high school teammate, Joe Savilla, to play football for the
Michigan Wolverines. Renda and Savilla both enrolled at the
University of Michigan.
The Michigan Daily depicted the two West Virginia recruits as something of an odd pair—Renda was a 5-foot, 4 inch
halfback, and Savilla was a 6-foot, 4 inch
tackle. Despite his small size (5 feet 4 inches and 152 pounds), Renda played for Michigan's freshman team in 1936 and for the varsity team from 1937 to 1939. His performance on the freshman team in 1936 was summed up as follows: "On the offense he runs like a frightened deer and is deathly with his tackles while on defense." Press coverage of Renda often focused on his short stature, and often referred to him as the "midget" from West Virginia. An
Associated Press story in 1937 reported that Renda was "just about the shortest first-string football player in the U.S." but noted that he "travels with the power of a tank." Michigan coach
Fritz Crisler called Renda the "greatest football player in America for his height." During the 1938 and 1939 seasons, Renda saw limited action, as Michigan had
Forest Evashevski and
Tom Harmon in the backfield. He became principally a blocking back in the 1938 and 1939 seasons. At the time of his death in 2005, the University of Michigan issued a press release stating, "Renda may have been one of the shortest football players in U-M history, standing only 5-3, but his speed and quickness plus his 17-inch calves made him an extremely tough running back to tackle." ==Assistant coach under Crisler==
