"Offensive linemen are to our draft what quarterbacks are to the NFL Draft." Former B.C. Lions coach Mike Benevides, who joins TSN's combine coverage this weekend, gave me that analogy several years ago and it has held true.

Historically, one of the best indicators of the relative strength of a CFL draft class has always been the depth and quality of available offensive linemen. For example, the best class in recent memory was 2008, where the first round of the draft produced three rookie O-Line starters and seven of the first twelve picks were offensive linemen.

This year, two top O-Line prospects, Alex Mateas (Connecticut) and Brett Boyko (Nevada-Las Vegas), will bypass the CFL Combine but here's a brief look at a few of the other prospects (listed alphabetically) who are causing scouts to call the Class of 2015 the best since 2008.

Sukh Chung (OG, Calgary, 6'3", 290 lbs.): Originally a member of the Class of 2014, he was among those CIS players reclassified to 2015 when the CFL adjusted its draft eligibility rules last year. After having to bide his time behind a deep group of veterans on the Dinos offensive line early in his career, he has developed into a two-time All-Canadian. Strong, aggressive, and tough, he plays with a definite edge and a desire to physically dominate his opponents.

Danny Groulx (OL, Laval, 6'7", 335 lbs.): His size is his most obvious asset but not by a long shot is it his only one. He moves surprisingly well for his size and also demonstrates the strength (29 bench press reps at the 2014 East West Bowl) to go along with his mass. He could garner NFL free agent interest.

Karl Lavoie (OL, Laval, 6'4", 285 lbs.): Manning the left tackle position for the Rouge et Or, he has been selected as an All-Canadian twice and an RSEQ All-Star three times. He possesses good footwork and is technically sound but will need to add weight to play at the next level.

Sean McEwen (OC, Calgary, 6'3, 300 lbs.): This two-time All-Canadian ranks as one of the most CFL-ready prospects in this class. While his outstanding technique and high football IQ are perhaps his greatest strengths, he is also physically impressive in terms of both strength and quickness.

Jacob Ruby (OT, Richmond, 6'7", 315 lbs.): This former tight end had originally committed to UConn before signing with the Spiders. He emerged as a four-year starter, primarily at left tackle, earning various All-Conference accolades over the last three seasons.

Unlike 2008, where current CFL starters Jon Gott and Luc Brodeur-Jourdain were drafted in later rounds, the 2015 O-Line class appears to be a little top heavy. The CFL Combine will present an opportunity for three NCAA Division 1 products, Campbell Allison (Eastern Michigan), and possibly James Bodanis (Michigan State) and Quinn Lawlor (Brigham Young) to prove themselves worthy of filling that void behind the top prospects.

David Beard (Alberta) would have also fallen into that category this weekend but the Second Team All-Canadian had to decline his combine invitation due to an injured wrist that required surgery.

As an aside, Dillon Guy (Buffalo), who had appeared among the Canadian Scouting Bureau's Top 15 prospects in both their September and December rankings, has been reclassified to 2016 after missing the entire season due to injury and taking a medical redshirt.
