The bad is that he didn't think his unit fared very well in Wednesday's scrimmage, but did fight back through the "dog days" on Thursday.
"I was disappointed that the twos moved up and down the field on our first unit (in the scrimmage)," Robinson said. "We were expecting a lot more. We still have to run to the football and execute. Our timing is a little off right now. But we go back and it has been a week ago since we started and we are much better than we were a week ago so we are making progress.
"…Now today, we are starting to get into the dog days," Robinson continued. "This was a two-a-day practice, but our kids came out in this afternoon's practice and really didn't care if it was the second practice of the day or not. It's the beginning of the dog days with all these reps and all these scrimmages and certain sections of practice start to wear on them physically. They have got to push themselves through it. We starting to execute a little more technique wise and we are starting to get our assignments down.
"Our legs are starting to go away from us, but they came out this afternoon and really practiced hard and put that behind them," Robinson added.
The defense would probably have had a better Wednesday if decorated defensive tackle Malcolm Sheppard would have been along for the ride.
But he was disciplined for basically contact during a non-contact drill that ended up with offensive lineman DeMarcus Love suffering an injury.
"It would nice if he would be able to do the things he is asked to do and execute during a team scrimmage type of thing," Robinson said. "He has got to learn how to do that. It is always nice to have Malcolm Sheppard on the field. We would have liked to have had him on the field during the scrimmage, but he has to learn to be disciplined and have some self control so he executes the defense and doesn't break the defense down."
Arkansas has been experimenting with moving defensive end Jake Bequette inside to tackle in certain packages.
"We are experimenting with that," Robinson said. "We are not sure who all four of our guys will be, but obviously it puts a defensive end with rush ability inside and maybe we can isolate him on a guard. That is still not etched in stone. We are still figuring out where those guys are, but that's our starting point."
Bequette is willing to give it a go, although he knows his 270 pounds are better outside than in on running situations.
"It is just a way of getting four of our best pass rushers on the field at the same time," Bequette said. "I think it will be a good deal for us. It is a learning process. It is definitely different. I have never done that before. But the more reps I get the more comfortable I get."
Robinson also likes what he sees from senior defensive end Adrian Davis.
"Adrian Davis is starting to buy into the things that we were selling at the beginning of a year ago," Robinson said. "He is starting to play harder. He is doing it on a more consistent basis.
"He is a young man that we looked at in the summer in our leadership seminars that we have with our players," Robinson added. "He was one of those guys and I think it made a big, big change in this young man's life. His habits are better. He is running full speed to the ball a lot better. Playing harder. He has made some growth, not only physically with the size that he has added, but he has made some growth as a human. He is only going to be better for our team because of it."
True freshman Colton Nash was moved from defensive end to tight end on Thursday because of the season-ending injury to Chris Gragg on Wednesday.
"Colton Nash is a guy whose future is still not set yet," Robinson said. "Because of our injuries on the offensive side of the ball, we needed to take that body and he has had experience at that position. We have got to do whatever is right for the team.
"He is a guy that is going to be a big young man," Robinson added. "There is no telling how big he is going to be and he is very strong and has nice size. He will be back into a learning process. Hopefully one day we will get him back, but if it doesn't happen, it doesn't happen. He was recruited as a defensive player, but we knew he had a tight end background."
Tenarius Wright, yet another defensive end, has bounced back and forth between linebacker and the DE spot.
"Tank (Wright) is a great kid," Robinson said. "He is going to do whatever is best for this football team. We started with him at middle linebacker and then when he came back to camp, we started moving him around in some of our sub-packages. He picked it up like that and it came back to him.
"He has displayed that he is probably more of a defensive end and he is loving every minute of it because he knows that is a position we need to utilize and he is one of those guys we look for," Robinson said. "He is a linebacker that can rush as a defensive end and is pretty strong in the run position."
Depth chart changes continued on a daily basis with Tramain Thomas moving ahead of Elton Ford at strong safety and Jelani Smith working with the first team linebacker corp.
"This morning we made a change at the safety position for example with Tramain Thomas starting at the strong safety, moving him in front of (Elton) Ford," Robinson said. "It is no big deal. Tramain is starting to become the player we expect him to be.
"We also had a linebacker shift with Jelani at the will linebacker," Robinson said. "Jelani is a guy who has demonstrated through practice that he is stronger and playing smarter and can deliver a blow. He is tackling well and starting to create for us on defense. We want people who are playmakers and who play physical. Jelani Smith has displayed that all throughout camp."
Smith thinks he got the reward for his work in Wednesday's scrimmage.
"Yesterday we had a scrimmage and I came out and I gave it all my effort," Smith said. " I had a couple of tackles, I knocked a couple of linemen down and I guess coach just gave me the opportunity and I appreciate that."
Smith said the constant shuffling of linebackers to work with the first team in the last few days will benefit the team down the line.
"It's been crazy, but I think it's a good thing for all of us because we're all getting reps with the (first-team defense)," Smith said. " That's where it's at there's where it's fastest at. So no matter who ends up starting, we got a feel for the game whenever we come off for the first game."
The list of injured players on Thursday afternoon included fullback Mitchell Bailey, defensive tackle Lavunce Askew and punter Britton Forrester while tight end D.J. Williams and wideout Marques Wade returned to practice with some non-contact work.
Freshman quarterback Brandon Mitchell was not at either practice because of a death in the family.
It was the annual watermelon day with former Razorback player David Johnson bringing up 130 watermelons from the Hope farm of Jackie and Martha May.
It was the 15th straight year that Johnson has done so.
Arkansas will have one 90-minute practice at 9 a.m. on Friday and then rest up for an extended scrimmage scheduled for 9:45 on Saturday morning.
