With a quarter of the NFL season in the books, already we have seen enough action to get a feel for performance in 2014, and where some players are outperforming their position on the depth chart.

All teams go into the season with a well-laid personnel plan, but often their fortunes are determined by how quickly they can spot the errors in that plan and make adjustments. They'll move away from underperforming players or simply toward those who are earning more snaps, targets or carries in limited action.

Here are 10 such players who demand more action this season.

Sankey

Bishop Sankey | RB | Tennessee Titans

Tennessee is running something of a backfield by committee, and starter Shonn Greene actually isn't performing too badly with his snaps. That being said, the standout performer in the committee is Sankey. Despite not yet managing a run longer than 18 yards, the rookie is averaging 5.1 yards per carry, 2.5 of which is coming after first contact. As with all rookie runners, the concern will be whether he can be trusted to protect the passer on non-running plays, but in that area Greene has not distinguished himself either this year, and Leon Washington has been the team's third-down back anyway. Time to tip the balance toward the rookie.
