[2] He was good enough to go on to the powerhouse Penn State Nittany Lions, and was later (on October 6, 2000) elected to the Plainfield High School Hall of Fame (as was Vic Washington, another football player, who coincidentally played against Liske in the CFL's 56th Grey Cup.)
Prior to his fifth-year senior season at Penn State, Liske was drafted in 1963 by both American professional football leagues, the NFL and AFL.
In 1967, he threw for 4,479 yards, a whopping figure for that era, and 40 touchdowns, the latter breaking Tobin Rote's league record of 38 in 1960 for Toronto.
In 1968, after a season comprising 4,333 yards passing and 31 touchdowns (though with 28 interceptions), he led his team to the 56th Grey Cup, losing a close and exciting game to the Ottawa Rough Riders.
Liske chose to return to the AFL in 1969, joining the Denver Broncos and playing seven games with them.
His combined total American professional record was: 50 games over five seasons, with 396 of 778 passes completed, for 5170 yards and 30 touchdowns with 46 interceptions.
Liske left the private sector in 1985 for the University of Washington in Seattle, where he started as an associate athletic director, with a focus on fundraising and promotions.
