Biggest problem with the Week 1 win vs Panthers?

Dude, the Browns looked and played like a 3 win team yesterday. Dallas didn't make them look that bad; THEY ARE THAT BAD.
So, despite them having a good season last year. You are going to judge their entire upcoming season on and single game, week 1, give no credit to the Cowboys and say they're not good because of some made up criteria in your head? Teams have bad weeks and some of them come in week 1. Watson hadn't played in a game since early November and the line didn't play well against one of the best defensive lines in the league. Those things happen.
