Editor's Note: In addition to contributing here, Derek also runs Scout The Draft - an NFL Draft analysis hub that you should head to immediately after reading this article. Derek has full reactions to the first round up, an updated big board, and an updated Top 200 list to check out.
The first round was a bit of a whirlwind. 10 trades, a couple of reaches, and a lot of great talent passed up. Here's a look at 20 top values going into the second round.
1. Courtney Upshaw - OLB/DE - Alabama - Intelligent, powerful end who can bull rush the passer, shut down the run and drop back. The tangibles aren't overwhelming, but on tape the guy can flat out play. One of the most complete defensive players in the draft.
2. Janoris Jenkins - CB - N. Alabama - Cue the off-field concerns, because there are certainly none on it. Jenkins is right up there with Morris Claiborne as one of the top two most explosive corners in the draft. He's extremely physical and effective in press, possesses ultra-quick hips to turn and run, elite click-and-close, can time and play the ball, and is a solid tackler. Needs t0 get his life together, but the right team could hit pay dirt with Jenkins in the 2nd round. A top-15 football player. Just doesn't have a top-15 record off the field.
3. Lavonte David - OLB - Nebraska - David is the most well-rounded, fundamentally sound linebacker outside of Luke Kuechly in this draft. He covers extremely well, is a sure tackler and tough to escape in the open field, explosive, quick to diagnose and close, and displays top notch instincts. Not much to dislike there. His size will scare some, but at 6'1, 230lbs, he's really not that small for today's weakside linebacker. An extremely effective pass-rusher at Nebraska, I can see him working in a 3-4 scheme as well, or even moving inside within that same scheme. Someone gets a great football player in Lavonte David.
4. Lamar Miller - RB - Miami - My 2nd rated RB in the draft, Miller's combination of speed, quickness and power make him highly intriguing, particularly in a zone scheme where he can do what he does best - cut and go. He's not going to break down in space and make a lot of guys miss laterally, but he's explosive through the hole and will pull away with 4.4 speed.
5. Cordy Glenn - OG/OT - Georgia - Huge, powerful mauler who is versatile and athletic enough to play either tackle or guard. Another first round player who presents great value from the top of the 2nd, on.
6. Jonathan Martin - OT - Stanford - Impressive pass-blocker with quick feet and good flexibility. You won't find a more consistent technician in pass protection than Martin, despite him lacking the natural power of the other top tackle prospects. Finesse or not, he'll protect the blind side and all indications are that he'll do it well. Those guys aren't necessarily a dime a dozen these days. Has some work to do as a run blocker.
7. Peter Konz - C/G - Wisconsin - Powerful, balanced blocker who gets off the snap quickly and targets extremely well all the way through to the second level. Tough to defeat in pass protection, and displays great awareness and ability to diagnose defensive schemes pre-snap. Starter-quality lineman at any of the three interior positions.
8. Devon Still - DT/DE - Penn State - Natural penetrator from the inside, with impressive raw power. Plays with his pads low, and knows how to generate leverage. Showed more consistency in '11, but still streaky at times and doesn't always seem to have the throttle pinned. Has potential to wreak some serious havoc on backfields at the next level if he can keep the motor running on all cylinders.
9. Rueben Randle - WR - LSU - Randle appears to have most of the traits that today's NFL scouts look for in a prototypical receiver. Size, speed, hands, clean routes and toughness after the catch. He also displays unique body control when adjusting to throws off his frame, and strong hands to secure in a crowd. The fact that A.J. Jenkins went before him was a huge surprise, but at least one of the first 4 or 5 teams at the top of the 2nd round probably won't mind.
10. Mike Adams - OT - Ohio State - Mike Adams is another massive tackle with elite power. He's surprisingly agile laterally for a guy his size, and maintains good discipline technically when sliding in the passing game or capping the edge as a run blocker. Off-field concerns have caused his stock to drop, but he's another guy who, if he can maintain focus on the game and get his act together, is a starting-caliber tackle or even guard at the next level, and relatively quickly.
11. Andre Branch - DE - Clemson - Quick end with prototypical length, high motor and good closing burst. Still developing a repertoire, but double digit sack potential at the next level.
12. Dwayne Allen - TE - Clemson - A "does everything well" tight end who plays fundamentally sound football. Athletic and quick off the line, and a good route runner with soft hands and consistent off-frame catch technique. Really good blocker too.
13. Jayron Hosley - CB - Virginia Tech - An absolute ball-hawk who QBs avoided in '11 after he picked off 9 passes the previous year. Not the prototypical size to take on huge receivers at the edges, but an off-man or zone corner who explodes to the ball with elite closing speed. Great hands and good vertical tracker.
14. Amini Silatolu - OG - Midwestern State - Tough, nasty and athletic lineman who relies more on power than technical precision at this point, but possesses all the tools to become a great interior lineman at the next level. Played left tackle at Midwestern State.
15. Mohamed Sanu - WR - Rutgers - Nothing flashy about Sanu, but he's a sure-handed, consistent route runner who's extremely physical and tough to bring down after the catch. A relentless competitor and intelligent football player who would be an ideal slot fit at the next level. Good value mid-2nd round or later.
16. Bobby Massie - OT - Mississippi - Inconsistent tackle with prototypical size, strength and athleticism. Needs technical work, but flashes starter potential and could compete immediately for a significant role on a tackle-hungry team.
17. Brandon Thompson - DT - Clemson - Good run-stuffing tackle who may lack ideal size to play the nose, but anchors extremely well and displays great vision to manage two gaps and plug holes consistently.
18. Jared Crick - DE - Nebraska - Not an elite athlete by any means, Crick simply finds a way to consistently get the job done. He's not a double-digit sack guy and won't blow blockers off the line, but he holds position, fights well with his hands and displays strong awareness and diagnostics. Gets around the ball and makes plays on effort.
19. Alshon Jeffrey - WR - S. Carolina - Big receiver with soft hands and extremely long arms. Not an elite leaper or as physical as his frame would indicate he should be, but has deceptive speed, tracks the ball well and will come down with it in a crowd. A big target with No. 2 capability in an NFL offense.
20. Jerel Worthy - DT - Michigan State - Flashes ability to absolutely dominate from the 1 or 3 technique. Natural penetrator with lower body power and strong, quick hands to rip and clear lanes. Highly inconsistent in technique and effort at Michigan State, but there's no denying the potential.
