Those were the two biggest things coming out of the Razorbacks' Basketball Media Day on Friday.
Clarke was suspended by Arkansas head coach John Pelphrey for the Red-White game a week ago and also the first exhibition game with Lemoyne Owen on Nov. 6 for violation of a team rule.
"Everybody makes mistakes and it really just depends on how I am going to deal with it," Clarke said. "I'm just going to have a good attitude and stay positive. I expect to be a team leader this year and be a more vocal leader this year and I am excited about this season."
"I'm not supposed to say anything," Clarke said. "It is something that happened in the past. It's over with and it's being dealt with now. We have moved on. I have talked to Coach and I have talked to my teammates and I am just moving on.
"It doesn't matter who I am," Clarke said. "I am nobody different. We are all the same people, we are all the same family. No one is better than anyone else. No one should be treated differently than anyone else."
Powell broke his foot during the summer and has been eased into practice.
"We've kind of had some good days and some days where we have had to be giving him off," Pelphrey said. "The only negative about him keeping that thing immobilized and stress free is that it is challenging to keep the kind of conditioning you want. We don't just want to throw him back out there and put him in a tough situation.
"The other guys have been out there 10-12 weeks getting after it and it's just a difference in conditioning level," Pelphrey added.
Powell and Pelphrey are looking toward also easing him into the season and that likely means missing both exhibition games – including Nov. 11 with Victory College.
Powell is gearing toward being ready to go with the season opener Nov. 18 against Grambling State.
"I would say that is still up in the air, but we are looking more at the 18th," Pelphrey said.
Powell said he wishes he could play, but wants to be cautious.
"I wish I could," Powell said. "It depends on what Coach and (head basketball trainer) Dave England think. I am just really looking more at the season. I don't have to be back for the exhibition season. It's not going to hurt me."
Powell said he has his good days and bad days when it comes to his injury.
"It depends on the day, how I wake up in the morning," Powell said. "Some days I wake up and it hurts and then like today it's okay and I might do a little bit more than I would do. I'm still pretty limited, but there is some contact."
Iowa transfer Jeff Peterson has been hampered by a hamstring injury and has not been practicing much either.
His availability for the exhibition games will be determined.
"I would say that is still up the air and we would talk about it when we get closer," Pelphrey said. "If he did play (in the first exhibition game), it would be very limited."
