The 2012 NFL Combine moves into its fifth day on Sunday, which is looking to be the most high profile day of the week. Running backs, wide receivers and quarterbacks run their position-specific drills as well as the uniform 40-yard dash, 3-cone drill, shuttle run and vertical and broad jump. Although the latter are meant to show a bit more about athleticism than football-specific skills, they can be money winners and losers for certain players.

Cal will be represented on Sunday by wide receiver Marvin Jones. The receiver flew under the radar next to Keenan Allen, but he has great hands and really stepped up the week of Senior Bowl practices. He is not a burner, but if he can put together some solid work at the various drills, he could see his draft stock sneak up. He already equaled Missouri's Jerrell Jackson for the top bench press performance among wide receivers. A few more strong performances on Sunday and he could take a big step forward.

Here's the full schedule for all groups. You can watch the majority of the action for this year's NFL Combine on NFL Network or streaming live at NFL.com.
