Each season in the Canadian Football League it seems as though relatively unknown first-year players at the start of training camp rise to prominence by the time the Grey Cup is handed out.

For example, over the least five years names like Solomon Elimimian, Chris Williams, Chris Matthews, Brett Jones and Dexter McCoil have made cannonball-sized splashes during their inaugural campaigns in Canada. That impressive list of names—and there are plenty of others you could add simply by going further back in time—proves at least one star is about to burst onto the CFL scene right before our eyes.

Identifying players that could be on the fast track to stardom in the CFL is a difficult task, but after surveying personnel men from around the league, a handful of talented first-year pro footballers stand out. So let’s take a look at five rookies who could make a substantial impact in 2015.

Henry Josey, RB, Toronto Argonauts

Josey rushed 174 times for 1,166 yards and 16 touchdowns in 2013, his final year at Missouri, the school’s first year in the NCAA’s vaunted Southeastern Conference (SEC). He’s a speedy (4.43 40), elusive runner, and his style should translate well to the CFL game. What’s more, Chris Steele, the Argonauts’ leading rusher from 2014, is on the six-game injured list and that gives Josey an opportunity to literally run away with the No. 1 running back job in Toronto.

Terrence Toliver, REC, Hamilton Tiger-Cats

At six-foot-five, Toliver has the size, speed and route-running ability to become the next great receiver in the CFL. He has a different body type than S.J. Green, but possesses the same ability to win on contested balls and make chunk-yardage gains. If he stays off the injury list, Toliver could put up a 1,000-yard season in his first year north of the border.

Sukh Chungh, OL, Winnipeg Blue Bombers

A number of teams rated Chungh as the top offensive lineman available in the 2015 CFL Draft and Winnipeg was able to land him with the No. 2 overall selection. The six-foot-four, 305-lb. young man proved he’s ready for the pros by putting forth consistent efforts during training camp and the pre-season. Chungh will start from game one for the Bombers at right guard, strengthening Winnipeg’s national talent pool and the Bombers’ o-line.

Nic Demski, REC, Saskatchewan Roughriders

Saskatchewan head coach Corey Chamblin called Demski “exciting” when first asked about him after the Riders chose him with the sixth-overall pick in the 2015 CFL Draft. A product of the University of Manitoba, Demski has been dubbed the most pro-ready offensive skill position player in his class. And it looks like he’ll be used in a variety of ways on offence with the Roughriders—he played running back and receiver during his Bisons career.

Telvion Clark, LB, Saskatchewan Roughriders

Saskatchewan has installed Clark as their starting weak-side linebacker to begin the season. The 25-year-old, who registered 139 tackles during his senior year at Towson University, is an instinctive player with a natural ability to read and react. Clark also has good range with the ability to effectively drop back in zone coverage and man up on a running back if need be. Clark plays fast sideline-to-sideline, so expect him to be a special-teams demon, too.
