It’s hard to be be critical of the Razorbacks after they destroyed Florida A&M 49-7, but there are still a couple of areas Arkansas should be concerned about.

Yes, coach Bret Bielema didn’t use the full playbook, and, yes, the Razorbacks were bound to make a mistake or two with it being Week 1. That still doesn’t excuse some of the miscues.

Last week, I wrote about the 5 things I wanted to see from Arkansas in its opener.

Some of the things came to fruition, while others didn’t.

Now, let’s look at five things Razorbacks fans should be wary of going into Week 2 against a TCU team that crushed Jackson State 63-0 in its opener:

1. Not getting to the quarterback

Arkansas had only three sacks in Week 1 against a weak FCS opponent. I know it was the first game with the new base defense, but the Razorbacks should have been in the backfield more.

The Razorbacks only averaged 1.92 sacks per game last season, horrendous by SEC standards.

They sacked TCU’s Kenny Hill three times in 2016. The Razorbacks defense has to up that number in Fayetteville on Saturday afternoon.

This is what needs to happen multiple times on Saturday.

If Hill has time, he’s going to be able carve up the Arkansas defense. Last week, Hill tossed an easy four touchdowns against Jackson State on only 23 passes. Last season against the Razorbacks, he threw for almost 400 yards.

TCU loves to push the tempo. New Arkansas defensive coordinator Paul Rhoads must be sure his defensive linemen are fresh.

2. Protecting Austin Allen

The Rattlers were able to get to the Arkansas quarterbacks twice. Once was Austin Allen, with five linemen blocking and only four defensive players rushing. That simply can’t happen.

It’s not just the sacks that add up. Allen was under an enormous amount pressure all last season. He didn’t face a lot of pressure during Week 1, but still faced more than he should have. Offensive line coach Kurt Anderson still has some kinks to work out with his front five.

Razorbacks fans don’t want Allen to be swarmed by players in purple, white and black. TCU only sacked Allen once last season, but that defense was below Gary Patterson’s typical standards. It will be revitalized in 2017, as evidenced by a five-sack performance in Week 1.

3. Late touchdowns given up

Arkansas blew a chance at a shutout when the Rattlers scored in the closing minutes of the fourth quarter. Though the Razorbacks had their subs in the game, the mindset should have been to hold the opposing team scoreless.

This might not seem like a huge deal, but considering that TCU scored the majority of its points against Arkansas in the second half last year, this situation shouldn’t be taken lightly. Bielema has to encourage his defense to finish strong, or the Horned Frogs might pull out a close win on Saturday.

4. Allen’s interceptions

Allen averaged 1.2 interceptions per game last season. He ended the 2016 season throwing 15 total. Some were a result of poor offensive line protection, like the one below.

Others resulted from his lackadaisical throws. If he continues to be careless at times, his interceptions will continue to hurt the growth of this Arkansas football team. TCU will take advantage of mistakes, just like it did against Jackson State.

5. Ryan Pulley’s injury

Ryan Pulley is out for the rest of the 2017 season after suffering a pectoral injury against Florida A&M. Before his injury, Pulley was Arkansas’ best option at corner. Many, including Bielema, think he has what it takes to play at the next level.

The Razorbacks secondary will suffer without him. Arkansas really doesn’t have a corner Rhoads can put on an island now. Look for TCU to take advantage with plays like this.
