This is the 31st in a 50-day summer series counting down the top players in Michigan State football history, as I see them. As with last year’s MSU basketball top 50, the criteria is performance and impact at MSU only, professional career irrelevant. Have your own opinion? Leave a comment or tweet at me @Graham_Couch.

No. 20 - T.J. Duckett

Running back, 1999-2001, Kalamazoo

The skinny: Duckett was both statistically productive and a memorable force during his three seasons at MSU. With a middle linebacker’s build and a wide receiver’s speed, Duckett carried MSU’s offense during his final two seasons and often carried defenders with him. Duckett’s 3,379 yards rushing are sixth all-time at MSU, second only to Sedrick Irvin among running backs who played fewer than four seasons. More telling, Duckett’s 5.44 average yards per carry for his career is better than any other running back with more than 250 attempts since Sherm Lewis (1961-63). - Read more at LSJ.com
