Seattle's next move

The Seattle Seahawks have remained in the headlines throughout the week, first by trading their 2013 first-round pick (and some other scraps) for dynamic WR/returner Percy Harvin (and extending him to a lucrative deal), then by signing DEs Cliff Avril and Michael Bennett to team-friendly deals. Reminder: this was a team that beat division-rival San Francisco -- the finest team in the NFC in 2012 -- by 29 points in Week 16. So what's next on the agenda?
