I think you are grossly overstating the defensive skill set. I think the Harris trade is going to be a bust. The guy wasn't that good when they let him leave and he wasn't that good when he was gone and he's barely good enough to start for this team. Peppers is here but he replaced the 2 best defensive ends from last year, offsetting much of that improvement. The other end is not very good. Tommie Harris is working off several years of excuses about injuries long in the past and has a long way to go to ever deserve the credit he is given by people who assume this defense is still potentially top notch. Having Urlacher back is great, but that's the only real clear cut improvement of talent, but even he is long past his prime. This defense is coming off three straight very disappointing seasons and hasn't added a single young starting caliber talent to the roster. I see very little chance for this defense to be better than average, and with all the pressure on old guys to step up and be the difference, I could easily see a decline. You should be concerned with every level of the defense. Again, the line is hardly the only real concern. The receivers have a year under their belts, in a different scheme. And experience isn't the only thing that matters. It's possible they will step up, but they haven't yet. The running back position is strong only because they changed backups, but whether the running attack is better is still a question. People are hoping for the return of what was a grossly overrated Forte from 2008, when his sub 4 yard per carry average did not impress. And the very weak line also plays a part with that problem, not to mention an OC who doesn't care much about the run. This is the unit that at least has a chance of being very good, but they could also be very bad, especially with that piss poor line. I'm not predicting a 12 loss season or a top 5 draft position, but the range of what this team might do is huge. The defense is out of excuses, has been bad for years and only upgraded incrementally at best. The offense may or may not gel in year 1 of a new system and the special teams aren't what they used to be. I could see 10 wins, I could see 10 losses. If they did go 5-11 I wouldn't be that shocked but an 11 win season wouldn't be that crazy either. It all depends on the offense and the offense depends on Cutler and the receivers compensating for a bad offensive line.
