You are correct again, Fever. Wells was forcing it last year and amazingly got lucky when the opposing Ds dropped easy INTs after INTs. Folks here thought he was good. He was just lucky. Very lucky. Now, he doesn't have as good of protection and he reacts ... not mobile... and makes bad decisions... accuracy has always been a problem... don't see that changing as time goes on.
And I also wondered how players being good were kept off the field on D when they should get playing time. Internal politics is a team killer. That may well be a problem as you pointed out. Coaches need to be smarter, but I have my doubts.
