3 Things We Learned from Andrew Luck's Stanford Pro Day

You think you've heard and read everything there is to know about Stanford's Andrew Luck?

Well, there's more.

The highly touted gun-slinger from Palo Alto held his pro day this afternoon and we all learned a few new things about this year's presumptive No. 1 overall pick. 

What were they? 

Let's get to it. 

1. He's Got a Much Better Arm That People Think

Before Stanford's pro day started, respected draftnik Mike Mayock stated he believed Andrew Luck has a "good" but not great arm. 

He compared it to the arm of Atlanta Falcons quarterback Matt Ryan. 

After Luck completed his throwing session, it's obvious that Luck's arm is stronger than that.

He threw into the wind for the majority of the afternoon (although some reports from analysts on hand said the wind was more side-to-side, than with or against) and his passes didn't flutter or lack a profound zip. 

Luck even declined to throw with the wind, according to the team's running backs coach. 

Because he threw the ball with such great velocity on every type of throw, the breeze never played a factor in the placement of his passes. 

At the end of the run through, Luck aired one out that traveled 70-yards in the air, right on target. 

Robert Griffin III makes slinging a 25-yard corner route look effortless—so does Luck. 

2. He's Mobile Inside the Pocket

After seeing his one-handed grab against Notre Dame and a handful of his long scrambles outside the pocket during his career, we were made aware of Luck's surprising athleticism and deceptive speed. 

His ability to move within the pocket is probably more important. 

Although Tom Brady pales in comparison to Luck in terms of athletic ability, he's flawless drifting in the pocket to make room to throw the football. 

With his quarterback coach George Whitfield using a broom, a far cry from the defensive lineman that will be pursuing him on Sundays, Luck was smooth in his lateral movements and steady when he decided to move up in the pocket before delivering. 

One of Luck's underrated specialties.

Coby Fleener Looks Fine

I didn't see anything else new from Luck, as he was the smooth operator I was expecting. However, one of his teammates did catch my eye.

Tight end Coby Fleener didn't participate in the running drills at the combine due to an injured ankle, but was a full participant in all the individual drills and was one of the four guys catching passes from Luck during his throwing session. 

At 6'6'' and 247 pounds, Fleener ran what some scouts timed as a 40-yard dash in the mid-4.4s. That's first-round caliber. 

He slipped on a cone drill, but calmly and more deliberately ran through it a second time. Following that drill, he had his ankle taped and didn't show any hitch in his gait the rest of the afternoon. 

Fleener did drop one seam-route pass but displayed tremendous hands by not allowing the football into his body on the rest of the throws his way. He even had the chance to show off his leaping ability on his final catch, a fade in the corner of the end zone that was a bit overthrown. 

If an NFL club deems that his ankle is 100 percent, he could be a late-first-round pick.
