ESPN's John Clayton is listing the Seattle Seahawks second to Green Bay among teams most likely to supplant San Francisco as the NFC team in the next Super Bowl.Separately, ESPN's Skip Bayless and Stephen A. Smith like the 49ers' chances for winning it all next season (see video above).A few things to remember, from my perspective:Health is huge: San Francisco and Seattle were both quite healthy through most of the 2012 season. Injuries caught up to both teams in the end.
