You are reaching & reaching badly
You do realize Treon Harris, Austin Appleby, & Luke Del Rio were the QBs at UF when CGC was the DC and they never avg more than 24pt/gm either season he was there and they still won 10 & 9gms, respectively, handing UGA one of its most embarrassing lost of the decades. Cmon man!
Let’s look at your theory for sec. Why did CPJ have such bad defenses then considering they often put up 30pts and held the ball for 35+ min. I mean he had Jet and Vad (who had the exact same rating as Dak)
As for data:
Pts/g (rank nationally)
‘13 23.3ppg (34th)
‘14- 21.7 (23rd)
‘15- 18.3 (11th)
‘16- 16.8 (6th)
Since you said teams like Florida are stockpiled with talent and would be good with anyone
‘20- 30.8 (74th)
Also, look at how many of DBs in the NFL.
There is a great amount you can criticize CGC on, but this is not the hill you should want to die on
As for CPJ's defenses I don't think anyone is going to say any of his coordinators did him any favors. Though in 2013 with Vad, Roof was basically the same at 22.2 PPG, in 2014 it was 25 ppg roughly. Both of these teams were teams where i'd say the CPJ offensive style helped keep our defensive numbers down. With 2014 being a turnover generator defense that helped as well.
For thought Florida's team defense ranking in 2013 and 2014 were 15th (in a 4-8 season!) and 19th respectively so yes Muschamp also being a defensive minded coach to a fault pretty much stacked those teams with defensive talent that was right there for Collins to come in and do something with, Muschamp also upset georgia in 2014 running all over them for 428 yards. Florida was admittedly a defensively stacked team when McElwain took over and brought collins in And collins to his credit took what he had, and did well with it.
As for DB's in the NFL. Yeah that part is impressive, gave me hope that we'd be seeing some of that DB whisperer. Can you honestly say you've seen evidence of that here? This year maybe its a covid anomaly who knows.
Some more fun stats.
Temple under Matt Rhule
2015 17th in total defense. 20 PPG
2016 11th In total Defense 18 PPG
Temple under Geoff Collins.
2017 58th Total Defense 25.3 PPG (Saw on Average 70.1 Snaps)
2018 66th Total Defense 27.1 PPG (Saw on average 79.2 Snaps)
So I think after diving into these stats and with your stats Ibe I am willing to concede that maybe Collins the Defensive Coordinator controlling only that aspect of the game and hyper focused on that and recruiting is one of the best defensive coordinators out there but Collins didn't recruit Keanu Neal, or Vernon Hargreaves. They were recruited by Will muschamp. And were juniors when collins came in and took over. So yeah I think having two probowl dbs does make the job a hell of a lot easier, then in 2016 well there was a reason all but one of florida's draft picks were on defense. The same was true the year those two mentioned went out (Brian Poole was even an undrafted free agent and he hasn't been a non contributor in the league) I was specifically referencing how much NFL caliber defensive talent the teams that Collins had the pleasure to coach at florida had not that the school itself was always going to pull that level of talent.
As for Collins as a defensive minded head coach the jury is still very far out on that. I honestly think his adherence to the cult of Tempo on offense is slaughtering whatever defensive stylings he is best at calling. Or he is being way too hands off when he really needs to call the defense.
