Gil Brandt, writing on NFL.com:

Chip Kelly (above) is a sharp guy who could make the auspicious start to his NFL head-coaching career truly special by capturing a title in Year 3. Yes, Philly traded away a 1,300-yard rusher in LeSean McCoy and let a solid receiver in Jeremy Maclin walk in free agency, but I think 1,800-yard back DeMarco Murray and promising rookie Nelson Agholor will keep the offense rolling. The Eagles’ defense, meanwhile, should be much improved with the additions of Byron Maxwell, Walter Thurmond and Kiko Alonso. Furthermore, if new quarterbackSam Bradford can stay healthy, which has always been the biggest question with him, he can have a huge impact. The bottom line is, Kelly knows what he’s doing.
