Sportsnet has ranked the top 50 CIS players all-time at the url below. While I disagree with quite a few of the rankings, the one that I dispute the most is ranking Mike O'Shea 45th. Even their own comment on O'Shea that "His final season at Guelph (1992) might be the best year from a CIS defender" doesn't make sense in terms of their ranking.

Mike O’Shea | Linebacker | Guelph 1989-92When you think of Guelph football, you think of Mike O’Shea — tough, resilient and daring on special teams. When you look at his body of work at both levels of the Canadian game, you could make a compelling argument that he is the greatest Canadian defender of all-time. O’Shea still holds the team record for career sacks with 19 and ranks fourth in total career tackles with 310. His final season at Guelph (1992) might be the best year from a CIS defender — his accolades that season included First-Team OUAA All-Star, CIAU All-Canadian and OUAA Defensive Player of the Year, and he led the Gryphs to a Yates Cup. He would go on to play 271 regular season CFL games and win three Grey Cups along the way. Pat Tracey, O’Shea’s defensive coordinator at Guelph, said: “He led the team in QB sacks but also had the speed and range to drop into coverage and play on the top running backs”
