It's late 2016, Diaco has finally killed his chances of returning as Head Coach. Think about what you were concerned about at that point and what you foresaw as potential for that team (lot of seniors on defense) in 2017 and medium term going into 2019.
Where are you now going into 2019 two and a half years later?
If you are not stupendously disappointed in HCRE2.0's eye discipline and execution you must have been very, very, very pessimistic in late 2016 (who saw no FBS wins in 2018?). With the talent he has accumulated as coaches and players someone give me some "how it could be worse" scenarios right now leading into 2019 so I can get a little more enthusiastic about HCRE2.0's execution to date.
I guess we could have no verbal commits for 2019, no QB's with FBS or FCS experience, no WR's with much career yardage, few TE's and a defense that was world class bad in 2018. Wait, isn't that what we have? So give me where HCRE2.0 has done GOOD.
