Heading into his Week 8 matchup with the Seahawks, no one seemed particularly high on Rams running Zac Stacy. The fifth-round rookie out of Vanderbilt had taken his first 50 NFL carries for 214 yards - a rather pedestrian 4.28 YPC.

Zac Stacy: 5-9, 216 pounds, 3,143 yards, 5.4 YPC, 4.55 40-yard dash, 6.70 three-cone drill, 4.17 short shuttle, 27 reps

Player X: 5-9, 215
