"We are getting closer to where we want to be on a Thursday," Petrino said. "No question, this was our best Thursday. It was the best as far as enthusiasm and close to perfection."
Petrino has always said the goal on the last heavy work day of the week was to have a "perfect Thursday."
Not everything is perfect with the Arkansas team. While it appears running back Dennis Johnson will play this week after missing the first two games with a hamstring issue, Petrino said the Hogs won't be at full strength. He noted that defensive end Jake Bequette (hamstring) and wide receiver Jarius Wright (knee) are out this week.
The head coach didn't mention all of the replacement starters for those expected to miss, but he noted that Chris Smith would step in for Bequette at defensive end. He said Smith is "excited" about his first starting opportunity.
Johnson will play. Petrino said the junior running back "would get some carries" against Troy.
"Dennis looks good and fast," Petrino said. "I worry a little about his conditioning. It's good to have him back. He helps in our running back rotation."
Petrino wasn't clear if Johnson would return kickoffs.
"Dennis wants to," Petrino said. "He got back there today. He's itching for that. We have not made a decision on that yet."
Petrino said both Bequette and Wright made progress in the rehab of their injuries.
"Both of them made significant improvement every day," Petrino said. "We hope they will both be back next week."
Petrino knows the Hogs face a significant challenge against Troy's fast defensive front.
"It's a great challenge for our offensive line," he said. "It's exactly what we need this week."
