Note: All combine times are unofficial until the NFL releases results following the final workouts of the week.

Here's what we've seen so far from the top quarterbacks at the 2012 NFL combine.

• Baylor QB Robert Griffin III posted unofficial 40-yard dash times of 4.38 and 4.41 seconds, and if his official time comes in under 4.4, he'll be the only quarterback other than Michael Vick to run that fast in pre-draft workouts.

His times look even more impressive when you consider the average for quarterbacks over the past four combines is 4.90. However, don't go thinking RG3 is strictly a run-first quarterback. He only scrambles and leans on his athleticism when the situation calls for it, which is one of the reasons he's risen steadily to the top of the draft board.

• A pair of big-bodied wideouts ran quick 40 times as well. Georgia Tech's Stephen Hill (6-foot-4, 215 pounds) clocked a 4.30, confirming the athleticism we see on tape. He's very raw overall, though, and at this point looks like a midround developmental prospect.

Notre Dame's Michael Floyd (6-2⅝, 220) came in at 4.42, and both he and Hill caught the ball well during drills. Floyd is in the first-round mix at this point because of his elite ball skills down the field, but both he and Hill didn't sink their hips and cut as sharply as some of the other receivers.

• Oklahoma State WR Justin Blackmon -- the clear-cut No. 1 receiver on the board -- did not run the 40, double-caught one pass during the gauntlet drill, and had two other drops, Still, he looked smooth and sudden at 6-foot and 207 pounds, and while his hands were inconsistent he showed the ability to aggressively snatch the ball out of the air at times.

• Arizona QB Nick Foles -- who is fighting for position on the board with the likes of Brandon Weeden (Oklahoma State) and Brock Osweiler (Arizona State) -- failed to stand out this morning. Unfamiliarity and a lack of timing with the receivers likely played a role, but he didn't show great foot speed in his drops and took too long to get the ball out on deeper throws. Michigan State QB Kirk Cousins, on the other hand, looked comfortable and confident and showed good accuracy in the process.

• Miami WR Travis Benjamin ran an unofficial 4.32 and tracked the deep ball well, but he had three drops in his first run through the gauntlet. Benjamin is undersized (5-1⅞, 172) and he projects as a slot receiver who can produce after the catch, so he has to show teams he can snatch the ball cleanly before looking to make a play. Not a good start.
