What is different from Chip Kelly and Andy Reid (In Time for Week 3)

Everybody knows the story about the 14 year head coach of the Eagles Andy Reid, The pass happy, jolly, NFC title cursed head coach that is now a Kansas City Chief. Also by now I am sure you have heard of that fast pace offense head coach from Oregon named Chip Kelly who has 63 points already from 2 games. Now with Kelly being Reid's replacement and all, what is the one big difference I have noticed between the coaches and their styles? Well I will tell you, This is going to be short and sweet and yes some may disagree but what I've seen from Chip Kelly since losing to the Chargers is adjustment to his coaching style (to an extent). He isn't focusing all on offense in practice and press conferences now its all defense. This is what coaches need to do yes HEAD COACHES not OFFENSIVE HEAD COACHES OR DEFENSIVE....sorry I hate when coaches are one sided and only focus on that side....then why are you a head coach? Chip Kelly and Billy Davis are making the necessary adjustments to be able to shut down Jamal Charles and the Chiefs Thursday night and that is something that Andy Reid could not do, and that is adjust on the fly!
