I was just reading up on Albert Hollis and Marcus Lattimore who had similiar knee injuries. It seems likely Jaylon Smith has a good possibility of getting back on the field, but to what degree? The injury ended both players careers, though they did play rb which is a different animal when considering speed, cutting, etc. The main difference is Jaylon tore 2 of his 4 ligaments while lattimore and hollis tore 3 while dislocating the knee. Whats unclear is the severity of the nerve damage to Smith and if he will regain full feeling and be pain free.
