John Cappelletti
In 1974, the Los Angeles Rams drafted John Cappelletti after winning the Heisman Trophy during his time at Penn State. He had a run of ten seasons in the NFL but lost one of them to a groin injury. He did not get a thousand rushing yards in a year. His best season was in 1976 as he got to carry the ball 177 times for 688 yards! The next year, he carried it 178 times for 588 yards. He retired after the 1983 season.
Johnny Rodgers
In 1973, the San Diego Chargers took Johnny Rodgers during the first round of the NFL Draft. They had high expectations of him, of course. In the end, he spurned them by signing with the Montreal Alouettes in the Canadian Football League instead. He spent four years with them before he finally made his debut in the NFL. Sadly, he only got one season in the NFL since a knee injury ended his career at an early age.
