I can't argue with a single thing you said. I fully expect the offense and punting to be better (seriously...how can they be worse?), which we all know will do nothing but help the defense. Only thing I'll say back to my point is that, of the metrics the defense was at or near the top in last year, scoring defense was not one of them. The 2018 unit finished #18 in the country in scoring defense....and I believe that number was pretty obviously driven in no small part by the horror movie that was the 2018 offense and special teams. So, when I say I don't think the defense will be "better", maybe a good offense/ST can help a little with the scoring defense number?
I just don't see how people can say a defense losing the kids we did will be BETTER than #1 in the country in TFL, #9 in the country in sacks, and #1 in the country in opponents 3rd down %. If your argument is that a better offense/ST will perhaps drop the scoring defense number from #18 (at 19.5 PPG), I might be able to agree with that. Or at least be optimistic about it. And of course, scoring/giving up points is really the only metric that matters. So if you want to tell me that with the returning talent on defense, better offense, and better special teams, Miami will give up less than 19.5 PPG this season, I might get on board there. But I just can't say the defense overall will be better....because giving up only 19.5 PPG in spite of the god**** abomination we saw in the other 2 phases is an incredible accomplishment, and I really can't get behind the defense being MORE dominant as whole when you're losing what we did, even though I am very excited to see the new kids play.
Bottom line, I think the defense will be fantastic. I just think the people who are saying it will be better are way too optimistic, and are also selling short the job that this defense did last year.
