Mackovic also had some praise for the Wildcat offensive line following the practice.
"The offensive line did a much better job in the running game, but we are still a long ways from being able to pass protect the way that we have to," Mackovic said.
The Arizona defense continues to make progress during every practice under the guidance of defensive coordinator Larry Mac Duff, who enters his first season at Arizona following four years as special teams coordinator for the New York Giants.
"Coach Mac Duff is doing really well," Mackovic said following Tuesday's session. "He has so much enthusiasm, he has a nice tempo, and he has a great understanding of the relationship between the offense and the defense. He is showing his NFL experience, and he demands excellence with everything he does."
Mac Duff spent 10 years with the Wildcats from 1987 to 1996 as defensive coordinator, and he was the architect of the pressure defense known as the double-eagle flex.
In other UA football news, Mackovic announced that he has dismissed senior fullback Tony Thompson (Pinole Valley, Calif.) from the team for failing to meet team responsibilities. Thompson entered spring drills as a reserve at the whip linebacker position but was then moved to fullback.
The Wildcats return to the practice facility on Thursday afternoon for their 11th practice session. Arizona is allowed 15 spring practices under NCAA guidelines and will conclude spring drills with the Spring Game on April 21, at 1 p.m., in Arizona Stadium.
All spring practices are open to the public. Most are scheduled on the practice facility at North Campbell Avenue and Enke Drive, across from McKale Center, but the Spring Game and some other sessions will be held in Arizona Stadium.
