Do you have your mind made up? I should probably let this die, but I'm a little hard headed (so my wife tells me sometimes).
How can both of the bolded statements above be true??? Tenuta had better players, but Roof has us better at defensive recruiting now. Tenuta (and Chan) had to deal with a complete overhaul of the coaching staff (which you keep saying would set us back) - did it set them back? CPJ was also a complete overhaul to the coaching staff and system - did it set him back with the offensive production? They also had to deal with flunkgate - They lose Kengi McNair - starting LB, Tony Hargrove - an NFL talent starting DE, Alfred Malone - a starting DT, Travis Parker - another starting DE/DT. This is after the coaching change which caused a terrible recruiting year in Chan's first recruiting cycle (he continued to coach the Dolphins through the playoffs, and got a very late start). It's also in the middle of a certain coach's tenure as Recruiting Coordinator, that most say was awful. He certainly didn't have a ton of his guys go to the league - pretty much comparable to what we have now and what we've always had - 0-3 in any given draft cycle. In his first year here, we were ranked around 50th, and then we were anywhere from 10th-29th every year thereafter.
I do think recruiting has been trending up, and I think Roof is a big contributor to that. But, doesn't this also serve as an indictment against him if the production isn't there (or if it doesn't get there at least in the next 2 years).
I think the question that has been posed to you is a good one. What would it take to convince you that Roof isn't the answer as DC? I can answer the inverse of that on my end. All it would take to convince me that he is the answer is bringing our defense into the top 40 in reasonable defensive metrics such as ppd and ypp.
Once again, I'm pulling for Coach Roof. The best thing that could happen to GT is for Ted Roof to find great success here as a defensive coordinator. I am not totally skeptical that this can happen. But, the data must and will tell the story.
