I don't think that's really what Kiper meant by that, but I would just remind everyone that it's smokescreen season. Of course the Bears would want people to think they might stay at #1. And of course other teams would want the Bears to think they might not be willing to trade up to #1.
Anyone who thinks the Bears won't have trade-down options is sorely mistaken. The closer we get to the draft, the more GMs will fall in love with particular prospects, some of whom will get in "I HAVE TO HAVE HIM" mode. Those are the GMs you can exploit. Chris Ballard is probably one of those guys. John Schneider and Brad Holmes (#4 and #5) may also end up in that category.
And if even one of those GMs wants to jump, the Texans have to seriously consider not letting it happen. Then AT THE VERY LEAST, it becomes worth it to trade back with *whatever* the Texans are offering, if you're worried about losing your pick at a top D player (b/c the Texans are obviously not going defense).
Long story short, there will be options, and at the very least, the Bears will be able to do a mild trade-back and still get assets and their pick of the litter. Or they can swing for the fences and go big on assets while having fewer high-draft options. Again, there will be choices available to the Bears. They're not staying at #1 if they don't want to.
