If nothing else, we at least learned this much from the Bears’ 41-21 loss to the Arizona Cardinals on Sunday at Soldier Field: defensive tackle Tommie Harris has a great future as an Ultimate Fighter.

There was Harris, after the fourth play from scrimmage, sitting on top of Arizona guard Deuce Lutui and slugging him in the facemask. Chuck Liddell would be proud.

That scenario best describes an undisciplined Bears team that couldn’t stop the Cardinals by land or the air on Sunday.

Tommie Harris gets an official escort from the field after his first-quarter ejection for punching Cardinals guard Deuce Lutui.

When it wasn’t Kurt Warner and Larry Fitzgerald carving up the secondary (will Lovie Smith please give Peanut Tillman and Zack Bowman some safety help!), it was Tim Hightower and Beanie Wells more than doubling the team’s league-low rushing average (64.9 yards per game) by halftime.

The boos rang out loud and clear by late in the second quarter, when the Cardinals were on their way to scoring  touchdowns on their first four possessions. Even FOX analyst Troy Aikman piled on, comparing the Bears defense to going against “7-on-7” drills. Ouch.

Yes, Bears fans have seen enough from this defense, and with a Thursday night game at San Francisco approaching, the meatheads will be screaming on all of the Windy City sports-talk shows this week for Mike Singletary as coach. And we all know that’s not the answer.

Here’s this week’s Bears report card, where you can watch the Bears’ sloppy tackling on the NFL Network highlight reel:

OFFENSE

Memo to Jerry Angelo: Please retool the right side of the line in the offseason, or your franchise quarterback will become a grease spot.

Jay Cutler has been holding on to the ball for too long, but RT Chris Williams and RG Roberto Garza let the pocket collapse and left Cutler face-planted on the turf at one point. Cutler was sacked 11 times last season, but already 19 times this year.

Put me in charge and I hit the free-agent market to retool the right side, moving Chris Williams over to learn from Orlando Pace how to play left tackle (Williams’ natural position). Wishful thinking: Why didn’t the Bears move up in the draft two years ago and take Ryan Clady, now with the Broncos? He does a pretty good job of protecting that Kyle Orton guy.

That said, Cutler and Greg Olsen finally have made the connection on the field that they have off of it, with Olsen catching three touchdown passes. They at least made things entertaining in the second half until Cutler’s interception with 6:41 left. Grade: B-minus.

DEFENSE

After being intercepted five times last week by the Panthers, Warner had five touchdown passes against the Bears. Tillman was lost covering Fitzgerald and got no help from the safeties.  Bowman didn’t fare much better in the second half with Tillman nursing a knee injury. With Harris out on the game’s fourth play, the pass rush was non-existent until Alex Brown took over midway through the fourth quarter.

When MLB Hunter Hillenmeyer went out for part of the game with a rib injury, it left the middle even softer for the Bears, which Arizona’s weak rushing game exposed. By game’s end, it was a matter of attrition for the Bears, with Hillenmeyer, Tillman and Al Afalava (shoulder) out or nursing injuries, and Harris in the locker room, probably punching the heavy bag. Grade: F

SPECIAL TEAMS

You know things are bad when Robbie Gould has a field goal blocked and Antrel Rolle returns it 59 yards to help set up a late first-half field goal by Neil Rackers. Gould had a nice tackle, which saved the special teams their first F grade this season.

Noteworthy: The Bears nearly botched a daring onside kick by the Cardinals in the second quarter when nobody wanted to fall on it. Usually a strength, special teams went through the motions this week. (Side note: I want Arizona punter Ben Graham’s job. Guy stood on the sidelines the entire first half.) Grade: D-minus

COACHING

Except for a poor reverse with Devin Hester, offensive coordinator Ron Turner called a decent game. I liked the fact that he came out throwing and opened up the playbook a bit and got Olsen involved. But this loss is on Smith and the defense. They weren’t prepared and played listless. It’s time to tell guys their jobs are on the line. Grade for Smith: F; grade for Turner: B
