The Hawks claimed the 2013 Bowl in a campaign that never saw Seattle under too much pressure because of an impressive defensive line. However, Wilson believes that his team can still do more to improve.
"There's a lot more ways we can be better," said Wilson, according to the NFL's official website.
"And there's a lot more ways that I can get better. That's the great part about it. I continue to try to stay focused on what I can control and continue to grow in every way possible."
Such was Seattle's dominance at the start of last season that the team managed 11 wins in their first 12 games.
