I agree with everything you said OP. Matt Ryan is great. I ride for him all day every day, but I just feel like we need a change of pace. Something to get excited about. We've been so bad, so long, I (like many others) just need something new to cheer for. I'm all for taking a Fields (if we can get him) and let him learn for 2 years under Ice.
That being said, I acknowledge that our defense is 100% the problem and always has been. They're terrible and pretty much all need to be replaced outside of maybe Foye and Grady.
