Read up some on the situation with the coach in Houston last year. He never really gave Brock the kind of support he needed to have a good chance to succeed.  They battled each other all season.  

And he was nothing more than a salary dump in Cleveland. He was never gonna play there.  They drafted who they wanted.  

That's not to say that Brock is a great QB or the answer all my himself.  He may not even be the answer at all.  But clearly Trevor struggles mightily and doesn't have the skills to mitigate weak OL play.  Not sure if Brock does, but they need a change.  The season could effectively be over in 3 weeks if they keep going like this.
