What about those lesser-known draft prospects that could make an impact in the NFL?Here's a sleeper pick for each position group to keep an eye on throughout the pre-draft process. QB: BRANDON BRIDGE, South Alabama. Outside of Marcus Mariota and Jameis Winston, the 2015 quarterback class is severely lacking. That being said, South Alabama QB Brandon Bridge could be a good late-round developmental project. The senior is a strong-armed, mobile passer, but he does have some issues with mechanics that need to be fixed. RB: DAVID COBB, Minnesota. Lost in all the talk about Melvin Gordon, Todd Gurley and Tevin Coleman is Minnesota senior David Cobb. Cobb isn't as flashy as some of the other running backs in this class, but he's a very well-rounded runner with good vision. He could be a solid contributor for most teams and is likely to be available on the second day of the draft. WR: JUSTIN HARDY, East Carolina. Just like last year, the 2015 draft class looks to be loaded with talented wideouts. As a result, talented receivers such as ECU's Justin Hardy could be available in the mid-to-late rounds. The senior has good hands and quickness and runs clean routes. However, Hardy checks in on the smaller side at 6-foot and 186 pounds, which limits him to more of a slot receiver role in the NFL. TE: JEFF HEUERMAN, Ohio State. Jeff Heuerman is about as reliable as they come in this class of tight ends. The Ohio State senior is a well-rounded, versatile pass-catcher and a capable blocker. So why is Heuerman flying under the radar? He battled a foot injury since the beginning of spring camp and generally has been underutilized in Urban Meyer's spread offense. OL: TY SAMBRAILO, Colorado State. Ty Sambrailo isn't as much of a sleeper in the sense that he could be a top-50 pick, but the Colorado State senior is someone who could garner more attention as the pre-draft process continues. He's athletic, moves well for a 6-5, 315-pounder and could find a home at one of several spots along the line, though he does have some strength concerns. DL: TREY FLOWERS, Arkansas. The 2015 draft should be full of quality defensive linemen, particularly edge rushers. Arkansas' Trey Flowers doesn't have the first-round projection like Nebraska's Randy Gregory or Kentucky's Alvin Dupree, but he could be just as good thanks to his disruptive hands, long arms and ability to play both the run and the pass. OLB: MAX VALLES, Virginia. Max Valles made the surprising decision to enter the draft as a true sophomore (he spent his first year out of high school at a military academy in Virginia). The 6-5, 240-pound linebacker has a long frame suitable for edge rushers. However, he's very raw and would need time to develop his pass-rushing arsenal. The potential is there, though, and Valles could thrive if drafted by the right team. ILB: ERIC KENDRICKS, UCLA. Eric Kendricks is a top-50 linebacker who could sneak into the end of the first round come April 30. The UCLA product and brother of Eagles linebacker Mychal Kendricks is on the smaller side at 6-foot and 230 pounds, but he has great instincts and a nose for the ball. Kendricks had three consecutive seasons with more than 100 tackles. CB: KEVIN JOHNSON, Wake Forest. Wake Forest often doesn't produce NFL-caliber prospects, which is why cornerback Kevin Johnson has flown under the radar through most of his college career. The 6-foot, 175-pound senior is a good cover corner with fluid hips and quick feet. He struggles in run support, but he could be a good fit on Day 2 for a team that needs help defending the pass. S: KURTIS DRUMMOND, Michigan State. The 2015 safety class is fairly weak, and there aren't too many well-rounded prospects aside from Alabama's Landon Collins. Michigan State's Kurtis Drummond is one of those few prospects. He has the ball skills to roam center and is good in run support despite his lean frame (6-1, 200 pounds).
