With a little more (sober) time to digest the game a little, while there many reasons for pessimism, but also some reasons for optimism as well. So I'll take both and run with them:
1. (Optimist) Its only preseason. Coaches want looks and do not really game plan. (Pessimist) Nagy and his offense was in mid-season form- no rythm, everyone making mistakes. Nagy as a playcaller is like a like a deaf man conducting an orchestra.
2. (Optimist) Well, of all three phases, it looks the the offense is the only one that hasn't gotten worse. (Pessimist) Well, of all three phases, it looks the the offense hasn't gotten any better (Pessimist).
3. (Optimist) Dline depth looks good. (Pessimist) Dline depth will be needed because the starting front cannot seem to play conistently or stay healthy.
4. (Optimist) Desai looked pissed on the sideline with the performance of his defense. Maybe that will translate to action to correct the lack of effort or result. (Pessimist) Desai's "roll over and rub my belly" defense made him look lost and clueless on the sidelines like someone stole his lunch money- and was powerless to do anything about it. Very Mel Tucker-esque.
5. (Optimist) Fields took a nasty hit on a play and bounced back. Indeed, he learned from and when he play happened again and deftly avoided the hit. (Pessimist) Fields took a nasty hit. Afterward he appeared a bit hurt. The Bears are 1 hit away from having a Dalton/Foles QBed team *shudder*
6. (Optimist) Special teams are working out a bunch of guys that will probably be on the street. Nothing to worry about there. (Pessimist) Special teams coverage and returns suck ass and will cost games if it is not fixed pronto.
7. (Optimist) All the things wrong so far can be fixed before the season starts- false starts, missed tackles, missed assignments. (Pessimist) From what we've seen so far, which phases has this team improved since last year ? In the NFL, if you are not getting better, you are getting worse...
