NFL rookies with the most to gain in training camp July 31, 2015 at 03:10 p.m. Daniel Jeremiah NFL.comLast year's rookie class was filled with guys who made an instant impact -- most of whom utilized training camp to develop as players and earn starting roles. As training camps kick into gear this year, all eyes will be on the top two overall picks in this draft class, Tampa Bay Buccaneers quarterback Jameis Winston (first overall) and Tennessee Titans quarterback Marcus Mariota (second). But there are several other first-year pros who will be intriguing to follow over the next month. Here are my top 10 rookies with the most to gain during training camp, arranged according to draft order:Kevin White, WR, Chicago Bears Draft position: Round 1, No. 7 overall. White was my top wide receiver in the 2015 NFL Draft, because of his combination of size (6-foot-3, 215 pounds), explosiveness and ball skills. However, he wasn't asked to run a large assortment of routes at West Virginia, and he'll need a lot of training-camp reps to get comfortable. Hopefully, he won't miss too much time with the shin injury that currently has him on the physically unable to perform list.Marcus Peters, CB, Kansas City Chiefs Draft position: Round 1, No. 18 overall. Cornerback is one of the toughest positions to adjust to at the pro level -- but Peters likely won't have much time to sit and learn, following the three-game suspension of veteran Chiefs cornerback Sean Smith. Peters would be wise to match up with new Kansas City receiver Jeremy Maclin as much as possible, in order to ready himself for the regular season.Donovan Smith, LT, Tampa Bay BuccaneersDraft position: Round 2, No. 34 overall. For first overall pick Jameis Winston to have a solid season at quarterback, he'll need Smith to protect his blind side well. To properly prepare for the season opener against the Titans, Smith needs to hog as many reps as possible during training camp; the Bucs don't have a backup plan.Preston Smith, OLB, Washington RedskinsDraft position: Round 2, No. 38 overall. Smith -- one of my favorite players in the draft -- will have a chance to compete with Trent Murphy for the starting OLB spot in Washington opposite Ryan Kerrigan. He can learn a lot by challenging himself against left tackle Trent Williams every day.Nate Orchard, LB, Cleveland BrownsDraft position: Round 2, No. 51 overall. Orchard has created a lot of buzz prior to the start of training camp. With a strong performance, he could nail down a starting job in one of the most underrated front sevens in the NFL.Maxx Williams, TE, Baltimore Ravens Draft position: Round 2, No. 55 overall. The Ravens are very high on Williams, but he needs to earn the trust of quarterback Joe Flacco with a strong training camp. His combination of toughness, soft hands and intelligence should ease the transition from college to the NFL.Ty Sambrailo, LT, Denver Broncos Draft position: Round 2, No. 59 overall. The Broncos suffered a big blow when left tackle Ryan Clady was lost to a torn ACL in the offseason -- and the pressure will be on Sambrailo to show he can take over. He struggled to anchor against power rushers in college, which is something he'll need to improve on during camp.Randy Gregory, DE, Dallas Cowboys Draft position: Round 2, No. 60 overall. Gregory has several challenges to overcome in training camp: He needs to adjust to a new position, learn a new system and avoid dropping the weight he's added over the last few months. He has top-tier talent, and I believe he will use training camp to quickly make the necessary adjustments.Gabe Wright, DT, Detroit Lions Draft position: Round 4, No. 113 overall. The Lions' interior defensive line was gutted in the offseason, with the departures via free agency of tackles Ndamukong Suh, Nick Fairley and C.J. Mosley. The trade for Haloti Ngata will fill one spot, but the other is wide open. Wright is raw, but he is very explosive and should fit well into Detroit's scheme. He'll have the opportunity to learn from two of the top defensive line teachers in the NFL in coaches Kris Kocurek and Jim Washburn.David Cobb, RB, Tennessee Titans Draft position: Round 5, No. 138 overall. Cobb was fun to study on college tape. He has excellent vision, patience and toughness. I think he's a real threat to emerge as the starter for the Titans if he has a solid training camp.
