Not sure I understand your question/concern.
Are you trying to tell us there is no guarantee we make it to the SB?
I think we all know this.
Are you trying to tell us our "overconfidence" can hurt the team?
I'm sure you realize thats silly.
This team is showing all the tell tale sign of a SB team.
8-1 record
Multiple big road wins Chicago, Philly, NY
Offense averaging 32 points a game lead by a QB performing at an MVP level
Defense that appears to be improving weekly
Why shouldn't we be excited and believe this teams going to the SB?
Because there's a "chance" it might not. There's some risk we may get let down. Get our feelings hurt and go BO-HO.
Should I not make plans for the weekend, because there's a chance I dont survive the commute home?
