First off, I should state for the record that I am not a pessimist by nature. I do not naturally focus on mistakes, problems, or the potential for disaster. I'm generally optimistic, looking at the positives (while not necessarily expecting them) and hoping for the best. And the Seahawks' 2010 season provided plenty of moments of validation for an optimistic Seahawks fan. After all, there were so many questions... Could Pete Carroll motivate NFL players the same way he did college players? Who was this John Schneider guy and what can we reasonably expect from a rookie GM? What on earth are we doing with Mike Williams, a guy who was a phenomenal bust and who ate himself out of the league 2 years ago?
As it turned out, Carroll's players loved playing for him and played hard, Schneider showed a nose for talent and a remarkable ability to work well with Carroll (which is a nice change for a Seahawks fan... a GM and HC that work together), and Williams turned out to be our best receiver. And there were plenty of other positives to note: Russell Okung's solid play when healthy, the acquisitions of Marshawn Lynch and Brandon Stokley, the career resurrections of Chris Clemons, Raheem Brock, and Red Bryant, the development of Ben Obomanu, Earl Thomas' promising rookie season, the amazing victory over the Saints in the Wild Card round of the postseason, etc.
But not everything was sunshine and puppies this year for the Seahawks. There was a lack of quality depth at nearly every position, which resulted in some ugly Seahawk football when starters went down (for example, Seattle's run defense falling apart when Red Bryant went on IR). 11 different offensive line combinations were tried over the course of the season. The playmaking promise of 2nd round pick Golden Tate never materialized. And perhaps the most frustrating thing about the 2010 Seahawks for fans was that the losses were never close - counting the loss in the Divisional Round of the playoffs to the Bears, the Seahawks lost 10 games by an average of 20 points per game.
Even with all of those issues just mentioned, I think there are three things that top the list of gaffes for the 2010 Seahawks:
