Pead displayed explosiveness, rushing for more than six yards per carry in his four seasons. Though he doesn't possess the size of an every-down back, Pead has developed a huge fanbase.
From National Football Post:
Exhibits a great burst to his game, plays fast when pressing space, and initially can outpace angles. Showcases an initial burst once he gets going and can outrun angles once he gets into space.
Runs hard, has some natural power when asked to fight through contact.
Pead's biggest flaw is his 5'10", 197-pound size. He probably isn't a 200-carry player in the NFL, and he won't be used much in the red zone.
However, Pead's game is great. He runs with power and strength while displaying great burst and agility. Outside of his size, there's little not to like about Pead as a player.
As a rookie, Pead probably won't see the field too much because his future is as a change-of-pace and third-down back. Unfortunately, Pead still needs to develop as a blocker, so he isn't yet ready to contribute right out the gate.
With a potentially interesting offense in St. Louis, though, Pead will be a solid backup for Steven Jackson and a good option out of the backfield on third down for Sam Bradford.
