1 Question Every Top Rookie Still Must Answer in Training Camps

Was Ryan Tannehill the correct selection for the Miami Dolphins at No. 8 overall?

That's just one of many questions to consider when debating what the top rookie prospects have to prove this and every season. OTAs certainly help get the newbies acclimated, but training camp and the preseason is where everything has to come together.

We'll delve more into Tannehill later, but first let's get to some burning questions about some other top 10 picks from the 2012 draft.

How quickly can Robert Griffin III develop under center?

If there's one knock on Robert Griffin III, it's his inexperience from under center. Spending quite a bit of time in shotgun for Baylor, the Heisman Trophy winner didn't need to worry about footwork and mechanics too often.

Now, RG3 does see the field well, puts the ball on a dime and has a rocket to fire in between small windows. That will be beneficial in the NFL, but how quickly he learns to go from under center to dropping back while feeling the rush and reading his progressions is the deal-breaker.

For one, the NFC East is overloaded with dominant pass-rushers. He needs to work from under center to set up the ground game. No read-option will work, as a defense can just put a linebacker spy on the running back.

Taking snaps from under center, however, allows for a stronger play-action bootleg and will limit any opponent's pass rush. And in the pass-happy NFL, if a defense can apply consistent pressure, no offense will move the ball effectively.

Is Trent Richardson the answer for Cleveland?

Cleveland certainly did themselves a favor by selecting Trent Richardson, but the Browns still need a lot more help on offense. The line is one area that must improve; otherwise, Richardson will see limited production as a rookie.

His presence in the backfield will definitely help take pressure off the quarterback and receivers, but the Browns don't have an impressive aerial assault anyway. So, one can reasonably argue that Justin Blackmon was a viable option for Cleveland as well.

Although the AFC North is a defense-dominant and run-oriented division, Blackmon could have stretched defenses to set up the run. Then the drafting of Brandon Weeden would have made more sense.

Richardson, on the other hand, does possess all the physical tools to save Cleveland, but the lack of a passing game and a stellar offensive line add even more pressure to the rookie running back.

Can Justin Blackmon immediately produce as a No. 1 WR?

Since he was available, the Jacksonville Jaguars snagged Justin Blackmon at No. 7 overall and spruced up their receiving corps for Blaine Gabbert.

That said, Blackmon may be expected to enter as the Jags No. 1 target, but his production will determine a lot of Jacksonville's success. Last season, the nonexistent passing game cost the Jaguars in many close games, so the balanced attack is needed.

The defense has top-three potential, and as long as Maurice Jones-Drew remains in the backfield, the ground game will be there to rely on. Still, Blackmon must prove he can put up numbers against single coverage and draw double-teams to help the passing game.

His immediate acceleration is strong, but not explosive enough to get that quick separation. He'll be great against soft coverage and working between the zones, but press coverage and aggressive defenses will isolate Blackmon by getting quarterback pressure.

Will Ryan Tannehill transition well into the NFL?

He played roughly 1.5 years at quarterback, rarely took snaps from under center and has durability flags entering the league; and yet Ryan Tannehill still went as a top-10 draft pick to the Miami Dolphins.

The good news, though, is that Tannehill does bring a strong arm, solid mobility and size to the position. So, he'll bode well on broken plays, making all the throws and taking a few shots here and there.

Unfortunately, his development will take longer because of that inexperience at the position and under center. Miami doesn't provide him with any true No. 1 receivers, and the AFC East presents impressive defenses for 2012.

Tannehill will have to learn quickly how to set up off play-action, scan through the progressions faster and improve at pre-snap reads. He was a risky selection regardless of the round, but going at No. 8 overall makes Tannehill arguably the biggest investment risk of the draft.
