We all know recruiting is an inexact science but some misses stick out more than others in college football. For all the excitement that comes with signing a five-star prospect, the success rate for even the most coveted prospects seems to be 50/50 at best.

In a recent ESPN article, college football recruiting analyst Tom VanHaaren listed 10 college football players that are running out of time to avoid being labeled a bust at the collegiate level. No specific criteria was listed for these players but the majority of them came with huge hype upon their entrance to college football.

Here are the players with SEC ties that were mentioned by VanHaaren:

Byron Cowart, Defensive lineman

Now playing for Maryland, Cowart signed with Auburn as the No. 3 overall prospect in the nation in the 2015 class. The Under Armour All-American signed with the Tigers after Will Muschamp was hired as the team’s defensive coordinator after being fired by Florida. In three seasons, Cowart has yet to record a sack and has a total of 15 tackles.

Martez Ivey, Offensive lineman

Ivey’s inclusion is somewhat odd considering he’s been a solid member of Florida’s offensive line since his arrival. The No. 2 overall prospect in the 2015 recruiting class was named as an All-SEC performer last season.

Blake Barnett, Quarterback

Barnett’s run at Alabama was a short one, having left the program midseason after Jalen Hurts won the starting role early during the 2016 season. Barnett then left for Arizona State and has since transferred again to USF. He was a five-star member of the 2015 recruiting class and the No. 2 pro-style quarterback in the nation. He’s thrown for 259 yards and two touchdowns in his career.

Daylon Mack, Defensive lineman

Mack had the benefit of lining up next to Myles Garrett and DaeShon Hall in College Station during the early portion of his college career. He failed to take advantage of the attention paid to those players, however, and hasn’t done much to replace their lost production in the lineup since. The No. 14 overall prospect in the 2015 recruiting class has 76 tackles and 2.5 sacks in his college career.

Ricky Town, Quarterback

One of the best examples of cautioning fans from buying into early recruiting rankings, Town was once considered the best quarterback prospect in the nation early in his high school career. His stock fell by the time his senior season was finished and USC ended up taking a lesser known prospect in the same class by the name of Sam Darnold. Town lasted about a week at USC before transferring to Arkansas. He never saw the field for the Razorbacks and now plays for Pittsburgh. He has yet to see the field after signing with USC as the nation’s No. 79 overall recruit in 2015.

Antonneous Clayton, Defensive lineman

Clayton still has two years to live up to his recruiting hype but so far hasn’t done much of anything of note in Gainesville. The No. 27 overall prospect from the 2016 recruiting cycle, Clayton has made 10 tackles and one sack in two seasons for the Gators.

Keller Chryst, Quarterback

Chryst had his chance to make a name for himself at Stanford but was benched last season following a terrible performance against Oregon State. While he does have an impressive record as a starting QB (11-2), he played with some of the nation’s best running backs and an all-around talented Stanford team over the previous two seasons. After losing his starting job, Chryst transferred to Tennessee. He signed with Stanford as the nation’s No. 51 overall prospect in the 2014 recruiting cycle.

Julian Rochester, Defensive lineman

Another interesting selection on this list, Rochester has been a productive member on Georgia’s defense since arriving in Athens. In his two seasons, Rochester has made 58 tackles and four sacks for the Bulldogs. He looks poised for a breakout season given the losses suffered on UGA’s defense this offseason. Rochester was the No. 70 overall prospect in the 2016 recruiting cycle.
