Scouting QB Ryan Tannehill

How good is Texas A&M quarterback Ryan Tannehill? And why is he one of the fastest-rising prospects in this year’s NFL draft?

These are questions many are asking leading up to April's NFL draft. Tannehill, once thought to be a second-round or late first-round prospect, is now projected to be in the top 20. There is speculation the Miami Dolphins could be interested in Tannehill, considering his connection with former Aggies coach and new Dolphins offensive coordinator Mike Sherman.

"Coach Sherman runs a West Coast offense, kind of drop-back passing, and well as moving the pocket," Tannehill said at the NFL combine. "I think that’s a couple of things I do well is move and throw on the run. He likes to move the pocket -- bootlegs, nakeds, whatever it may be. Get outside the pocket and make throws downfield. I like what he did, and we’ll see what happens."

Here is how Scouts Inc. graded TannehillInsider:

Accuracy (average): "Flashes good anticipation and ability to deliver the ball to a spot before the receiver makes his break. A bit unpolished with mechanics though, especially with footwork. Does not always step to target or throw in balance, which can lead to him missing the mark. Also has room for improvement with ball placement, and will force receivers to adjust on routine throws. Much more accurate with short-to-intermediate throws than as a deep thrower at this point."

Release, arm strength (average): "Possesses a three-quarter sidearm release where he almost pushes the ball. However, gets it out quickly and can release the ball accurately from a variety of launch points if need be. Low release point brings up some slight concerns about batted balls at the NFL level. Arm strength is adequate-to-good, and can make all the NFL throws. Does not have elite ability to stretch the field vertically though."

Scouts Inc.'s profile isn't too flattering for a top 20 pick, but it did grade Tannehill a 93, which is tied for 13th among all prospects. Does Tannehill have potential to be a franchise quarterback?
