2012 NFL Combine: Day 4 Winners and Losers

Day 4 of the 2012 NFL Scouting Combine is winding down, and the close of Sunday's action brings with it the conclusion of the event for offensive players, as the wide receivers, running backs and quarterbacks took to the field at Lucas Oil Stadium.

As is always the case when the offensive skill positions take part in the combine, the results of those drills can have a significant impact on a player's draft stock.

Here's a look at both the players that shined in the combine spotlight on Day 4, and those that wilted under its heat.

WINNER: Michael Floyd, WR, Notre Dame

Notre Dame wide receiver Michael Floyd was already considered a first-round prospect after an outstanding 2011 campaign that saw the 6'3", 220-pound senior catch 100 passes for over 1,100 receiving yards.

Floyd did nothing to hurt his stock at the combine, running a solid 4.47 in the 40-yard dash and displaying a 36.5-inch vertical jump that goes very nicely with his lanky frame.

LOSER: Alshon Jeffery, WR, South Carolina

Wide receiver Alshon Jeffery was one of the most polarizing players at his position heading into the combine.

After dispelling rumors about his conditioning by showing up in Indianapolis at a trim 216 pounds, a strong 40 yard-dash likely would have cemented the 6'3", 216-pound junior as a first-round pick in April.

However, for unknown reasons Jeffery chose not to participate in any receiver drills at the combine Sunday.

Unless he has an outstanding outing at South Carolina's pro day, Jeffery's first-round aspirations may well have gone up in smoke.

WINNER: Robert Turbin, RB, Utah State

Utah State running back Robert Turbin was wildly productive while racking up nearly 1,800 total yards and scoring over 20 touchdowns as a junior for the Aggies last year.

However, after missing almost two full seasons to injury in college, questions remained about Turbin's durability and straight-line speed.

Turbin received a clean bill of health in medical examinations in Indy, and after reeling off a very quick 4.44-second 40-yard dash, given his 5'10", 222-pound frame and excellent display of upper body strength with 28 reps on the bench press, Turbin likely boosted his stock at least a full round in the upcoming draft.

LOSER: Kendall Wright, WR, Baylor

Baylor's Kendall Wright was one of the most productive wideouts in all of college football a season ago, catching 106 passes for 1,663 yards and 14 touchdowns.

Given Wright's prowess as a deep threat, it was widely expected that the 5'10", 196-pound senior would run one of the fastest 40-yard dashes at the combine.

Wright must have gotten up on the wrong side of the bed Sunday, however. While his lethargic 4.61-second time in the 40 may not be a death knell for his draft stock, it likely killed any chance Wright had of being the first WR off the board.

WINNER: Stephen Hill, WR, Georgia Tech

Stephen Hill didn't get the chance to showcase his abilities as a receiver much in college, as Georgia Tech's run-heavy option offense limited the 6'4", 215-pound junior to only 28 receptions in 2011.

However, Hill also averaged a gaudy 29.29 yards per reception last season, and the speed he displayed on Sunday while running a 4.36-second 40-yard dash (tied for fastest among wide receivers), combined with his height, undoubtedly thrust him onto some NFL teams' radars.

LOSER: Vick Ballard, RB, Mississippi State

Mississippi State running back Vick Ballard is a powerful ball-carrier that averaged over six yards a carry while rushing for nearly 1,200 yards a season ago.

The 5'10", 219-pound Ballard is one of a logjam of running backs that should come off the board in the middle rounds in April.

Unfortunately for Ballard, if the combine is any indication, he may be selected towards the back end of that run on running backs, as the 4.63-second 40 time the senior posted isn't going to do anything to quiet Ballard's doubters.

WINNER: Brian Quick, WR, Appalachian State

Wide receiver Brian Quick may have played at a small school at Appalachian State, but that didn't stop the 6'4", 220-pound wideout from posting big numbers last season, when he hauled in 71 passes for 1,096 yards and 10 touchdowns.

Quick came up big when he needed to at the combine as well, posting a respectable time in the 40-yard dash, displaying excellent leaping ability, and moving himself into possible third-round contention.

LOSER: Brock Osweiler, QB, Arizona State

With Andrew Luck of Stanford and Robert Griffin III of Baylor electing not to throw at the combine, and Texas A&M's Ryan Tannehill sidelined by a foot injury, the stage was set for some lesser known signal-callers such as Brock Osweiler of Arizona State to steal the show in Indianapolis.

The 6'7", 242-pound junior was unable to capitalize on the opportunity however, as a foot injury of his own prevented Osweiler from working out, costing him any chance of working his way up draft boards until the Sun Devils' pro day.

WINNER: Kirk Cousins, QB, Michigan State

Most of the talk around the 2012 combine where quarterbacks are concerned centered around the fact that Andrew Luck of Stanford and Robert Griffin of Baylor weren't throwing or the blistering 40-yard dash time turned in by Griffin.

However, no signal-caller that actually took the field for passing drills helped his draft stock more Sunday than Michigan State's Kirk Cousins, as the 6'3" 214-pound senior was reportedly very sharp throwing the ball from both three and five step drops.
