The NFL regular season is still more than three months away, but the rookies are already in full swing preparing for the first season at the next level.
In the case of the Tennessee Titans, there are a few rookies who will play major roles under a new coaching staff led by Ken Whisenhunt.
Here are the biggest storylines surrounding Titans rookies during OTAs.
Zach Mettenberger Not 100 Percent
The Titans decided to wait until the sixth round to take a quarterback in the draft, but Zach Mettenberger appears to be a steal at this early stage.
Mettenberger wasn't able to "fully step into throws" at Titans rookie minicamp, according to Kevin Patra of NFL.com.
The small risk involved in taking Mettenberger is mainly due to his knee injury he suffered in his final season at LSU. If that injury ends up being a long-term problem, then this pick will essentially be wasted.
It will also leave the Titans in a really bad place if Jake Locker ends up flopping in 2014.
Greg Pogue of Fox Sports Tennessee says that Mettenberger is still impressing Whisenhunt despite not being at 100 percent. It makes you wonder what Mettenberger is capable of once he finally gets over this nagging injury that shook up his senior season.
Monitor this situation as the offseason rolls along. Mettenberger probably won't overtake Locker before Week 1, but he has a great chance at starting at some point during his rookie season. He's that talented.
Bishop Sankey Will Miss Some OTA Action
Getting as much time and preparation as possible is critical for rookies before making the giant leap from the college ranks to the NFL.
You have to applaud Sankey for finishing off his education before moving on to the NFL. A lot of the transition to the NFL involves being mentally prepared, and Sankey appears to be a high-character addition to the Titans organization.
This time missed shouldn't have anything more than a minor impact on Sankey's progress into the Titans offense. He figures to be a focal point of the run game ahead of Shonn Greene and Dexter McCluster.
Sankey is a three-down running back who will benefit the Titans greatly after losing Chris Johnson to the New York Jets.
Taylor Lewan's Legal Battle
The Titans threw many people a curveball by drafting Taylor Lewan at 11th overall and bypassing a few other pressing needs.
There's no questioning Lewan's value as an offensive tackle at the next level. He plays with the physicality and mean streak that makes for a great offensive lineman.
However, you can't help but be a little troubled by Lewan's current legal battle that involves an alleged assault on two Ohio State fans.
In the end, this probably gets washed away. This isn't something that should raise any serious red flags. Adding another offensive tackle is fair criticism, but judgement should be reserved on Lewan's legal battle.
With that said, it needs to be resolved before training camp begins. Lewan has the potential to leapfrog an aging Michael Roos (31) or Michael Oher for a starting role.
DaQuan Jones Could Be Top Pick of Draft
Everyone is focusing on the picks of Lewan, Sankey and Mettenberger. People can't forget about the Titans' fourth-round pick of DaQuan Jones.
The massive Jones brings versatility to a defense that will be playing a mixture of 4-3 and 3-4 defenses, according to John Glennon of The Tennessean.
Jones brings some much-needed size to this defensive line. He will push Karl Klug and Mike Martin back on the depth chart, and he will bring a ton of value in clogging up the middle to stop the run.
This pick was widely overlooked among the seven draft picks the Titans made. He brings four years of productive experience from Penn State and plenty of coveted versatility.
Avery Williamson Grew Up a Titans Fan
The Titans chose to address linebacker in the fifth round of the draft by taking Avery Williamson out of Kentucky. He brings a ton of great intangibles to his game and will be a solid special teams player right out of the gate.
His ceiling could be even higher if he develops just a little bit more.
The Titans currently have some questions at inside linebacker with the likes of Moise Fokou and Colin McCarthy. Both of these guys could end up having bounce-back years, but Williamson is definitely the next guy in line to take over.
Peter Smith of WithTheFirstPick.com has Williamson as his favorite pick of the Titans' draft class.
Many of the Titans' draft picks were focused more on the long-term future, and Williamson is one of them.
