Cobourne became the Montreal Alouettes's starting running back in 2008, in which he finished the season with 1,557 all-purpose yards and was named a CFL East Division All-Star.
He followed this up with an outstanding 2009 season where he rushed for 1,214 yards and 13 touchdowns, culminating in CFL All-Star recognition and being named the MVP of the 2009 Grey Cup.
In football, he rushed for 1,400 yards and 32 touchdowns as a junior, but suffered an anterior cruciate ligament injury early in his senior season.
[1] Cobourne entered West Virginia right after Amos Zereoué, the star running back from 1996 to 1998, left early for the NFL.
Cobourne also made 1st-team all-Big East and broke Zereoue's freshman rushing yardage record at West Virginia.
His best performances of the season though came against Virginia Tech, whose defense was ranked #1 in the nation against the run, when he ran for 133 yards; and against Pitt, when he rushed for a then Mountaineer Field record of 210 yards, which was the best single-game performance for a WVU freshman.
Cobourne again finished in the top 20 in the nation in rushing and earned second-team all-Big East honors.
Cobourne was also named team MVP and was the only player to rush for over 100 yards against the national champions, the Miami Hurricanes (132).
Cobourne, Amos Zereoué, and Steve Slaton are often considered the greatest backs in school history.
While also playing linebacker, Cobourne became one of the league's most feared returners during an exhibition game against the Toronto Argonauts.
The next game after the injury, he rushed for 33 yards on seven attempts while backing up former college rival Payton (who played at Miami; versus Cobourne's WVU).
After these 2 performances, the Alouettes decided to name Cobourne the starter for the rest of the season and cut Jarrett Payton.
As Montreal then defeated Toronto, Cobounre posted his fourth-straight 100-yard rushing game with a 107-yard performance off of 16 carries.
Cobourne opened up his second season as the full-time starting back for Montreal with a 19 carry, 107 yard performance with a touchdown against Calgary.
Then against the Saskatchewan Roughriders, Cobourne produced a career-high 146 rushing yards and two touchdowns on 25 carries.
He won the Most Valuable Player award in the 97th Grey Cup when the Montreal Alouettes defeated the Saskatchewan Roughriders 28–27 on November 29, 2009.
[7] After Martell Mallett suffered a torn achilles tendon, the Tiger-Cats elected to re-sign Cobourne for the 2012 season.
In the off-season, he is a businessman, operating and acting as president of Pre-Game Enterprises, a sporting goods company based out of Charleston, West Virginia.
For now, the company is selling T-shirts, caps, and mouthpieces with Cobourne's signature slogan, Chill Son, in the shape of a football.
