Big 12: Justin Isadore

Earlier this morning, we broke down half of the big surprises and big busts from the 2009 recruiting class in the Big 12. Let's take a look at the rest of the Big 12.

Oklahoma State

Best surprise: OL Levy Adcock (Claremore, Okla.)

Adcock came to Oklahoma State as a juco transfer but had a quiet beginning to his career. He was the Pokes' No. 4 tight end in 2009 but moved to the offensive line and won the right tackle job, emerging as one of the Big 12's best lineman, and certainly the league's best in 2011. He was a first-team All-Big 12 selection and an All-American as a senior.

Biggest bust: RB Dexter Pratt (Navasota, Texas)

Pratt came as the only ESPN 150 member of Oklahoma State's 2009 class, but left the team in the spring of 2010. He was the nation's No. 15 running back and No. 139 overall recruit, but redshirted his first season on campus. He transferred to a junior college but was arrested in April 2011 on drug charges. That came less than two years after Pratt was arrested on a misdemeanor drug possession charge in July 2009.

Texas

Best surprise: S Kenny Vaccaro (Brownwood, Texas)

Vaccaro was just the nation's No. 42 safety and entered Texas more highly ranked than just two of the Longhorns' 20 signees. Still, he emerged as a playmaker throughout his career. He was a three-year starter and a two-time All-Big 12 selection, earning All-America honors as a senior. It's not as tangible of an honor, but for my money, he's been one of, if not the hardest hitter in the Big 12 the past two years.

Biggest bust: QB Garrett Gilbert (Austin, Texas)

Gilbert might be one of the biggest busts in Big 12 history. He was a hometown talent and the nation's No. 2 quarterback and No. 11 overall recruit, rated higher than guys like AJ McCarron and just behind talents like Matt Barkley and Manti Te'o. He showed big promise in the 2009 national title game against Alabama when Colt McCoy was injured, but threw 17 interceptions in Texas' 5-7 nightmare season in 2010. He returned in 2011, but threw two quick interceptions as Texas fell behind BYU. Gilbert was benched as fans booed him off the field, and he never saw any more time. He underwent shoulder surgery later that year and transferred to SMU, where he started and threw for 15 touchdowns and 15 interceptions in 2012.

TCU

Best surprise: DE Stansly Maponga (Carrolton, Texas)

Maponga came to TCU as the nation's No. 111 defensive end and ranked higher than just a handful of TCU's high-school recruits. He was a freshman All-American in 2010 after redshirting and became a full-time starter, earning all-conference honors. In 2011, he was a first-team All-Mountain West honoree and was TCU's only preseason representative on the All-Big 12 team. He battled injuries, but still had 6.5 tackles for loss and three sacks, a year after making nine sacks.

Biggest bust: OLB Justin Isadore (Beaumont, Texas)

Isadore redshirted in 2009 but left the team after the season and transferred to Stephen F. Austin. He was the nation's No. 38 outside linebacker and the Frogs' second-highest ranked recruit. After transferring to the FCS level, he still has yet to record more than 20 tackles in a season.

Texas Tech

Best surprise: S D.J. Johnson (Austin, Texas)

Johnson was a middle-of-the-road recruit in a Texas Tech class that was just OK, but he emerged as a huge contributor and a three-year starter for the Texas Tech defense. He was an All-Big 12 honoree in 2010 and 2012 and racked up 90 tackles in 2012 for a much-improved Texas Tech defense under coordinator Art Kaufman.

Biggest bust: OLB Brandon Mahoney (Keller, Texas)

Mahoney was the class' highest-ranked signee and the nation's No. 13 outside linebacker. At one time, he was committed to Oklahoma, but Texas Tech made a swipe on the recruiting trail, but Mahoney didn't pan out. He left the team in August 2010 after redshirting in 2009.

West Virginia

Best surprise: S Darwin Cook (East Cleveland, OH)

Cook was the nation's No. 89 safety and didn't attract much attention on the way into Morgantown, even though he's got a pretty crazy backstory. He emerged to be a two-year starter at safety for the Mountaineers and a three-year contributor, providing the biggest defensive highlight of 2011 when he returned a fumble 99 yards for a touchdown in the Orange Bowl win over Clemson.

Biggest bust: WR Logan Heastie (Chesapeake, Va.)

Heastie was the nation's No. 19 receiver and only Geno Smith (known by recruiting services as "Eugene Smith" ... awesome) was rated higher in the Mountaineers' class. Heastie, though, never caught on with the Mountaineers and reportedly didn't take to offseason workouts and didn't do much to impress coach Bill Stewart. Heastie transferred in April 2010.

Kansas Jayhawks

Recruits: 24

Breakdown: 21 high school, three junior college.

Positions: 5 DL, 3 OL, 3 WR, 3 LB, 3 CB, 3 S, 2 QB, 2 RB

Where they came from: Texas 11, Kansas 4, Florida 2, Oklahoma 2, Michigan 1, Illinois 1, Missouri 1, Nebraska 1, Ohio 1.

The stud: S Prinz Kande, Euless, Texas (Trinity High School) -- Hard-hitting performer who is expected to immediately beef up production at one of the Jayhawks' primary weaknesses.

Recruiting-class sleeper: CB Tyler Patmon, Cedar Park (Vista Ridge) -- Undersized player who should mature after arriving at college. And his football genes are strong with both grandfathers and two uncles all playing college football before him.

The one who got away: LB Justin Isadore, Beaumont, Texas (Ozen) -- Athletic playmaker who was attracted to TCU by the Horned Frogs' underrated defense. He could have helped the Jayhawks, either as a speedy outside linebacker or a strong safety.

Needs addressed: Quarterbacks, defensive line, secondary.

Didn't need much help: Tight ends.

Scouts Inc. grade: C- (10th in the Big 12, fourth in North Division).

My take: Mark Mangino has done a better job than anybody in the Big 12 in developing under-recruited players once they arrived at college. He appears to have more talent with this recruiting class than most of his previous classes -- particularly in the secondary. And considering the Big 12's recent aerial bent, that's a wise place to concentrate.
