<em>(Bucky Brooks ranking: 1; Daniel Jeremiah ranking: 1)</em>
<strong>Previous rank:</strong> 1
Bosa was having a dominant season before suffering a core muscle injury against TCU 10 days ago. He is still the premier defensive talent in college football. -- DJ
<em>(BB: 2; DJ: 2)</em>
<strong>Previous rank:</strong> 3
Herbert saved his best showing for the biggest stage. He was deadly accurate against Stanford over the weekend and also displayed his impressive mobility. -- DJ
<em>(BB: 3; DJ: 3)</em>
<strong>Previous rank:</strong> 2
The most disruptive interior defender in college football continues to enchant scouts with his exceptional first-step quickness. -- BB
<em>(BB: 4; DJ: 5)</em>
<strong>Previous rank:</strong> 4
Ultra-athletic defender with the versatility and explosiveness to play multiple positions along the defensive line. -- BB
<em>(BB: 8; DJ: 4)</em>
<strong>Previous rank:</strong> 5
Davis is an ultra-physical player in the run game and he flashes upside against the pass. He stands out on a very destructive defensive line. -- DJ
<em>(BB: 6; DJ: 6)</em>
<strong>Previous rank:</strong> 9
Big, athletic tight end with the size and playmaking ability to create mismatches in space. He fits the prototype that racks up catches in bunches in the NFL. -- BB
<em>(BB: 5; DJ: 8)</em>
<strong>Previous rank:</strong> 6
Playmaking cover corner with a knack for finding the ball. Williams will be the next LSU standout to make his mark in the league as a lockdown CB. -- BB
<em>(BB: 7; DJ: 7)</em>
<strong>Previous rank:</strong> 20
Lawrence is healthier this season and it shows. He looks more explosive and is moving much better laterally. -- DJ
<em>(BB: 9; DJ: 9)</em>
<strong>Previous rank:</strong> 23
Junkyard dog on the island with the size, length and instincts to stymie top wide receivers with his aggressive approach. -- BB
<em>(BB: 10; DJ: 11)</em>
<strong>Previous rank:</strong> 8
Grier is incredibly efficient and I love the poise he displays in the pocket. There are other quarterbacks with more size/arm strength, but he is operating at a high level. -- DJ
<em>(BB: 11; DJ: 12)</em>
<strong>Previous rank:</strong> 19
One of the cleanest pocket passers you'll find in the collegiate ranks. Lock not only displays A-plus arm talent, but he is a rhythm thrower capable of dropping dimes with timing, touch and anticipation. -- BB
<em>(BB: 15; DJ: 10)</em>
<strong>Previous rank:</strong> 16
Stidham will miss some throws on occasion, but I still love his skill set. He can create plays with his legs and he's an effortless thrower. -- DJ
<em>(BB: 14; DJ: 15)</em>
<strong>Previous rank:</strong> Unranked
Polished cover corner with a technically sound game and a nasty demeanor. Murphy can thrive in any scheme as a lockdown corner with the athleticism to play from distance or nose-to-nose. -- BB
<em>(BB: 13; DJ: 17)</em>
<strong>Previous rank:</strong> 17
Alabama has an impressive stable of backs, but Harris continues to be very reliable. He has excellent vision and finishes every run. -- DJ
<em>(BB: 18; DJ: 14)</em>
<strong>Previous rank:</strong> 18
The LSU standout might be the best athlete in college football. He possesses a combination of size, speed and explosiveness that could make him a star at the next level. -- BB
<em>(BB: 16; DJ: 16)</em>
<strong>Previous rank:</strong> Unranked
I haven't done a full workup on Wilson, but I love his combination of instincts and range. He is always around the football. -- DJ
<em>(BB: 20; DJ: 18)</em>
<strong>Previous rank:</strong> 14
Brown isn't going to record a blazing 40-yard-dash time, but he has strong hands and is ultra-competitive after the catch. -- DJ
<em>(BB: 17; DJ: 21)</em>
<strong>Previous rank:</strong> 24
It's hard to find disruptive defenders with A-plus size, strength and movement skills, but Brown is the total package at defensive tackle. The 6-foot-5, 325-pounder (school measurements) is a five-star playmaker capable of taking over the game in the trenches. -- BB
<em>(BB: 12; DJ: NR)</em>
<strong>Previous rank:</strong> Unranked
The gunslinger has lit up defenses with his pinpoint passing skills. Haskins is a rare find as a big-armed quarterback who has the patience and discipline to pick apart defenses with an assortment of quick-rhythm throws. -- BB
<em>(BB: NR; DJ: 13)</em>
<strong>Previous rank:</strong> Unranked
Jones was playing at a very high level before suffering an injury (broken clavicle) in Week 2. He has ideal size, athleticism and arm talent. -- DJ
<em>(BB: 22; DJ: 19)</em>
<strong>Previous rank:</strong> 7
Experienced edge blocker with the footwork, quickness and technical savvy to hold his own against elite pass rushers. -- BB
<em>(BB: 23; DJ: 20)</em>
<strong>Previous rank:</strong> 15
Big, athletic defensive tackles with playmaking ability are hard to find. That's why scouts are enamored with Jones' potential as a disruptive penetrator with explosive first-step quickness and burst. -- BB
<em>(BB: 19; DJ: NR)</em>
<strong>Previous rank:</strong> Unranked
Harry is similar to A.J. Brown in that he lacks elite speed, but he makes up for it with toughness and ball skills. He reminds me a little bit of Anquan Boldin. -- DJ
<em>(BB: 21; DJ: 24)</em>
<strong>Previous rank:</strong> Unranked
Smith is the next great Stanford tight end. He has made several contested catches in the early portion of the season. -- DJ
<em>(BB: 24; DJ: 22)</em>
<strong>Previous rank:</strong> 12
Defensive coordinators can't wait to get their hands on guys like Wilkins, who can play anywhere from nose tackle to defensive end in a three- or four-man front. Wilkins' versatility and athleticism should make him a hot commodity when the draft rolls around in April. -- BB
