"I've seen a guy dominate a game with Leonard Little from that position," Smith said. "Most quarterbacks are right handed, so a lot of action he's right in his face. Normally a lot of people say blindside and that makes a little bit sense, but he's not playing against the best pass rusher."
Haynes has looked awkward at times at left end, which did facilitate the move. He had a strong practice on Monday, as he reached the quarterback on more than one occasion.
"Really I was pleased with how the defensive line rushed the passer today in particular Michael Haynes," Smith said. "We moved him to the right side of the ball, seems like he's a lot more comfortable over there."
Brown has played left end in college and during his rookie year with the Bears. While he might be able to use his speed to his advantage against slower right tackles, playing the run could be a different story.
"It's just on me to teach them how to use their hands to get off of blocks," said defensive line coach Karl Dunbar. "I think they're big enough and strong enough to do it."
Brown returned to practice too soon from a calf strain. He's still having trouble going putting his weight on his toes, which can affect him getting off the ball.
Without Brown, Israel Idonije is the first string left end. At 6-foot-7, 308 pounds Idonije has the size to play the run and proved he can get to the quarterback as he had two sacks in the preseason opener due in part to the help of fellow Canadian Alain Kashama.
"It was really not just me, It was teamwork," Idonije said. "Both times Alain flushed him and I just came in and just cleaned it up."
Kashama had also been impressive at right end, but a sprained ankle kept him out of practice Tuesday. His status for the second preseason game against the San Francisco 49ers is in doubt.
The undrafted free agent out of Michigan has the athletic ability to rush the passer. He only started six games for the Wolverines as he got lost in the shuffle.
Despite the recent compliments from the coaching staff Kashama isn't taking anything for granted when it comes to making the 53-man roster.
"A free agent is very easy to get rid of, so I'm always at the bottom as far as I'm concerned," Kashama said.
With the play of Idonije and Kashama over the past week, Claude Harriott has seen his amount of reps diminish of late especially when it comes to the first team.
Dunbar said Harriott's lack of action has more to do with trying to examine what kind of players the team has in Idonije and Kashama.
"You've got a draft pick and you know what he can do because you've watched him all year," Dunbar said. "These two young guys, Idonije and Kashama, we've never seen before, so we want to get a look at them."
To sure up an area of perceived weakness, the Bears made a trade for a defensive end on Tuesday. The team acquired Quinn Dorsey via trade with New England for a conditional draft pick in 2006.
The 6-4, 260-pounder wasn't likely to make the New England roster. So the fact that GM Jerry Angelo went out and traded for Dorsey, an undrafted free agent out of Oregon, shows the perceived lack of depth at defensive end.
