It's too bad about Rachal's family problems and I hope they are resolved.
The dude along with the rest of the Chicago Bears offensive line damn near got Jason Campbell killed. I thought the pounding the Saints gave Mike Vick a few weeks ago was bad, but the Bears made the Eagles o-line look like five blocks of granite.
Rachal washed out in San Francisco and if he washes out in Chicago, he's going to wash out of the NFL. If you're "emotional and need constant positive reinforcement" you had better be playing at an All-Pro caliber level to get that kind of special treatment and Rachal is so far from that it's not funny.
Dude may need to get on some meds, seek counseling or whatever, But when it's time to strap it on and step it up, you can't wimp out or you will get OWNED.
