I really don't think so. Only way the "I told you so" will be intense is if the team actually doesn't flat out suck and is competitive, and if so... let em brag, they were right, the coaching staff turned out to be great and the front office knew what they were doing. That is an outcome that most here would feel great about.
Meanwhile, if we're the worst team in the league, why brag? A large portion here thinks we are the worst, the consensus among NFL prognosticators says this is a horrid roster, the odds makers think this is the worst team in the league... I really don't see how "I told you so" will carry much weight when it is backed by the opinion of 98% of the population.
That said... I don't get ya'll that think this team won't be trash. We're trading for 3rd string QBs and tossing em into the starting lineup 5 minutes before the season starts... holy moly is this team going to suck.
