RB Doug Martin, Boise State: Martin came into this week as a player many thought would be a lock as a third-round back. After showing off his chiseled physique in the weigh-in and backing it up with a great week of practice, Martin is a player that some talk about as being a late first-round guy. He runs low to the ground, has good vision, and is a good receiver out of the backfield. He’s versatile enough to help out a team as a kick returner as well. Martin was the only back on either roster that looked good in every facet of the position in practice. Although the methods used to conduct both the North and South practices limited the opportunity to see running backs do what they do best, Martin’s downhill mentality, quickness and physical style came to the fore. He’s the only running back after this week where there are zero questions about his future chances as a three-down player.
