Geroy Simon broke into the CFL in 1999, and spent two seasons with the Winnipeg Blue Bombers. Simon put up good, but not outstanding numbers in those two seasons, but then he was playing behind Milt Stegall. Simon had 34 catches in 10 games in his rookie season and 51 in 17 games in his second season.
Simon became a free agent after the 2000 season, but didn't sign with BC until October of 2001, picking up 14 catches in 6 games. 2002 was another good, but not great season with 50 catches in 17 games. 2003, however, was the season that Geroy Simon really took flight. He had 94 catches for 1687 yards to win his first West and CFL All-Stra onours. To show it was no fluke, Simon improved on those totals in 2004 with 103 catches for 1750 yards and a second West and CFL All-Star selection. Simon "slumped" in 2005 to only 89 catches and 1322 yards - numbers that would be a great year for just about any other receiver in the CFL. If anyone thought that Simon was slowing down, he had his best season yet in 2006 when he caught 105 passes for 1856 yards to earn his third West and CFL All-Star selections, and was also named the Outstanding Player in the CFL. 2007 was another "off" season for Simon with 72 catches and 1293 yards - his fifth straight season over a thousand yards receiving. Simon was once again a West and CFL All-Star in 2007.
Simon would run his thousand yard receiving streak to nine thourgh the years 2008 to 2011. Simon add three more West All-Starst to his collection in 2008, 2009 and 2011 and two more CFL All-Stars in 2008 and 2011. Simon's consecutive thousand yard season string was broken in 2012, partly due to some injury problems, but Simon did pass his old team mate Milt Stegall to become the all time CFL receiving yardage leader.
Despite that and his lengthy resume as one of the best receivers in the league, Simon was no longer wanted by BC after the 2012 season, or it would be a reduced role if he did stay. At age 37, the Lions wanted someone younger and GM Wally Buono let Simon shop himself around for a trade. The Saskatchewan Roughriders were happy to deal for Simon, sending receiver Justin Harper and a third round draft pick to BC for Simon.
