The price? 2 first round picks (18th this year and the Bears 2010 pick), a 3rd round pick, and Kyle Orton in exchange for Jay Cutler and a 5th round pick.
That's a high price to pay for a quarterback. Kyle Orton did a pretty solid job for Chicago last year, but apparently they wanted the upgrade and liked Cutler enough to make the move. Personally, I think Cutler could be a franchise quarterback, but that's still a high, high price to pay.
The Jets also didn't have anyone like Orton to throw in. If the Broncos didn't like Kellen Clemens or Brett Ratliff, and they probably didn't, then matching the Bears offer would have been near impossible and would have almost certainly had to go through a third team.
