Tevin Mitchel gets beat deep against Rutgers in Week 4.
The Arkansas secondary was abysmal in 2012, giving up 285.8 yards per game through the air and ranking 113th in the NCAA. Though it has made improvements, concerns still remain.
In the first three games against lesser competition, the Hogs allowed only 140.0 passing yards. However, over the last two games against good teams in Rutgers and Texas A&M, the Razorbacks allowed 607 yards and five touchdowns.
The measuring stick through five games has to be greatly dependent on the last two performances against high-level programs.
From here on out, Arkansas' schedule is loaded with heavy hitters and the secondary hasn't responded to the rise in competition.
Rutgers quarterback Gary Nova carved the unit up for 346 yards. Despite holding Johnny Manziel to 261 yards, much of it can be attributed to the Aggies' top receiver, Mike Evans, being limited for most of the game due to a leg injury.
He finished with six catches for 116 yards and two touchdowns. Before he injured his leg, Evans had five receptions for 93 yards and both scores in the first half.
The secondary has slowly descended in total passing yards allowed after a fast start, currently sitting at 47th in the nation.
The last two weeks for the unit have to be a major concern for Bielema and defensive coordinator Chris Ash. With some prolific offenses ahead on the schedule, things need to get turned around in a hurry.
