@Simpleton is right.
The sober view is that this was a coin flip game against a team that's probably very similar to us quality-wise, and we were on the road. They had to make 3 50+ yard FGs to beat us by two points. They're about a top 5-6-7 team in the league and so are we. Is that a reason to cry that everything sucks, everyone is a loser, etc.? I don't think so. Of course it would be more fun to be a top 2-3 team, but we're slightly below that. It's just what we are.
My disappointment is I'm afraid everything has been squeezed out of Dak that we can get. He's good to very good, but he just isn't the guy to carry a good but flawed team -- and most are -- to a Super Bowl against top defenses. I'd hoped that the new system, etc. would work through these periods he has where his brain locks up, and I think he has made progress, but it looks like it's not enough.
