17. BENGALS — G Cordy Glenn, Georgia: Cincinnati is in need of interior offensive linemen, and Glenn is the best one if DeCastro is off the board. The Bengals, who pick again at No. 21, could also go cornerback or running back.
18. CHARGERS — CB Dre Kirkpatrick, Alabama: The Chargers might make a bold move to trade up and get Barron. If not, they could hang back and fortify their secondary with Kirkpatrick, or pick up a pass rusher.
19. BEARS — DE Nick Perry, USC: Rod Marinelli, the Bears defensive coordinator, made a special trip to USC to work out Perry and that could be a good sign for the Trojans standout, who had 91/2 sacks last season.
20. TITANS — WR Michael Floyd, Notre Dame: Kenny Britt has only played in 15 games over the last two seasons with the Titans, and Nate Washington isn't a No. 1 receiver. Floyd is a big target who could step in and make an immediate impact.
21. BENGALS — RB David Wilson, Virginia Tech: Wilson is compact, ultra-quick and elusive. He would be a strong complement to free-agent acquisition BenJarvus Green-Ellis. Boise State's Doug Martin is another option. However, both Wilson and Martin could be around in the second.
22. BROWNS — QB Brandon Weeden, Oklahoma State: Depending on how things shake out at the top, Weeden could go as early as No. 4, or fall out of the first round completely. GM Tom Heckert really likes him.
23. LIONS — T Riley Reiff, Iowa: If the Lions can't move up high enough to get Barron, Reiff would be good value here. He'll likely go earlier because teams covet tackles, but he's more of a right tackle playing on the left side.
24. STEELERS — LB Dont'a Hightower, Alabama: Hightower is big (6-3, 266) and extremely physical. He's not great in coverage, but a lot of teams like what they see in him. He could be a fit for the Ravens, too.
25. BRONCOS — DT Jerel Worthy, Michigan State: The Broncos hit the jackpot by taking Von Miller last year, but passed on Marcel Dareus to do so. They still have a pressing need for interior defensive linemen, and Worthy fits the bill.
26. TEXANS — DE Whitney Mercilus, Illinois: With Mario Williams gone, the Texans need more players who can put heat on quarterbacks. Mercilus had 16 sacks last season, his only year as a starter. Is he a one-season wonder?
27. PATRIOTS — DT Kendall Reyes, Connecticut: Reyes might not be an elite athlete but he's what scouts call a high-effort player who won't disappoint the Patriots with his attitude and work ethic.
28. PACKERS — DE/OLB Shea McClellin, Boise State: It's a lofty comparison but some scouts have likened McClellin to Clay Matthews. The Packers finished with 29 sacks last season, tying them for 27th in the league. McClellin had a combined 26 over the last two seasons.
29. RAVENS — G Kevin Zeitler, Wisconsin: With left guard Ben Grubbs signing with New Orleans, the Ravens need someone to fill his shoes. Zeitler would be a good fit. If the Steelers don't take Hightower, the Ravens might.
30. 49ERS — WR Stephen Hill, Georgia Tech: The 49ers say they've already picked their player for this spot, possibly meaning this could be a surprise selection. The 6-foot-5 Hill has great size but is a gamble coming from a run-first option offense.
31. PATRIOTS — C Peter Konz, Wisconsin: Konz is the best center in this draft, and his career would flourish under offensive line coach Dante Scarnecchia. The Wisconsin standout has been slowed by ankle problems, however.
32. GIANTS — TE Coby Fleener, Stanford: The Giants have plenty of needs along the offensive line, but Fleener would be a good fit. Imagine that: a first round that starts with Luck, ends with his top touchdown-scoring pass catcher.
