In context when compared to other Canadiens centers.
Ralph Backstrom very lite. Without the skating or offensive skills,
Easily replaced by a much better defensive center once traded to Washington. The center was Guy Carbonneau.
Somewhat similar to Tomas Plekanec. Less offensive talent, better defensively. Neither was a banger but did neither was known to shy away. Above average skater, excellent balance, on ice awareness, ability to leverage bigger players.
Basically what at that time was known as a typical Peterborough Petes center. Most effective with the Canadiens when he played with Bob Gainey and Jim Roberts, all were Peterborough Petes Alumni. New the system the proper positioning for the three forwards and executed it perfectly. Gainey was the dominant physical force - able to physically dominate transitioning/first pass defencemen yet get back to cover the dangerous opposing RW. Roberts was the hustling defensive player, first retreating winger. Jarvis was the defensive center setting the geometry and the depth of the forecheck.Neither was much of a shooter, Jarvis and Roberts had wet ammo, Gainey had an excellent shot but no accuracy.
