A graduate of Florida State University,[1] Giardino joined the Ottawa Rough Riders in 1967. Rushing 3 times for 15 yards and blocking a kick in his rookie season[2] was good enough to win the Gruen Trophy as best rookie in the East (this at a time when only Canadians were eligible for the award.) He later became a starting linebacker and depenable back up fullback, his best year being 1971 when he rushed for 201 yards.[3] On defense he intercepted 6 passes, returning 3 for touchdowns, and took fumble recoveries back for another 3 TDs, including 146 yards in 1972, still the second best in CFL history[4] On offense he rushed for 536 yards and caught 44 passes during his career. He was a Grey Cup champion three times: 1968, 1969 and 1973. Finally, he was the head coach of the Ottawa Sooners junior team in 1994, leading them to a 7 win and 2 loss season.[5]
