Jennings season.
It might be the factor of an entire season vs. one game's performance idk.
I would have been curious about a matchup between Jennings' season and Marshall's season. I think then I might lean to Marshall since Jennings had a great D-line and Marshall was hamstrung by poor offensive gameplanning, spotty run support and lack of another consistent receiving threat on the field. But one game vs. Jennings' awesome Prop Bowl season? Jennings gets my vote.
