The Seattle Seahawks came up just one yard short of defeating the New England Patriots in the 2015 Super Bowl. Pete Carroll's decision not to run Marshawn Lynch still remains a mystery to most. Still, this Seahawks squad is even better than last season having acquired star tight end Jimmy Graham from the New Orleans Saints.

The Seahawks could use a bit of an upgrade at the wide receiver position having ranked 27th in passing yards last season. Chris Matthews may become a breakout star, but he only has one year remaining on his contract.

Here are five free agent wide receivers the Seahawks could consider signing:

1. Michael Crabtree

Former No. 10 overall draft pick Michael Crabtree has played his entire six-year career with the San Francisco 49ers. He hasn't quite lived up to that status, having just one season over 1,000 receiving yards, but he's still a quality wide out. This potential signing would be very interesting, considering the whole Richard Sherman "mediocre" comments after the NFC Championship game. The Miami Dolphins recently talked to Crabtree, so he may not remain a free agent for much longer.

2. Wes Welker

It feels like so long ago that Wes Welker was considered the best slot receiver in the league, and a top 10 receiver overall. Tom Brady and Julian Edelman have changed that in New England. It doesn't look like the Denver Broncos are going to re-sign Welker, but the Seahawks could use a little slot receiver like him for third downs at a cheap price. Welker has a concussion issue, so the Seahawks shouldn't offer much guaranteed money. If they can get Welker at a discount, a Russell Wilson-to-Welker connection could be great to watch.

3. Reggie Wayne

It's been an amazing career for Reggie Wayne. The future Hall of Famer has accomplished nearly everything one could ask for including winning a Super Bowl, eight 1,000 yard seasons, and he has amassed over 1,000 career receptions. Wayne may choose to retire an Indianapolis Colt, but if he wants to play one more season in search of another Super Bowl, the Seahawks would be his best option. Wayne would bring veteran leadership to Seattle, but the bigger question is, does he want to return for another season?

4. Greg Jennings

Greg Jennings' legacy will always be with the Green Bay Packers, but he still played well with the Minnesota Vikings for two seasons. Even over the last two seasons on a mediocre Vikings squad, Jennings accumulated 1,546 receiving yards and 127 catches. Not elite, but he can certainly help the Seahawks' vertical passing attack. Jennings has also been reliable having missed just one game in the last two seasons. The Jacksonville Jaguars have shown interest in Jennings.

5. Brandon Lloyd

Brandon Lloyd isn't a possession type receiver, having never caught 80 balls in a season in his 11-year career. But, he's fast. Lloyd could provide an extra deep threat for Russell Wilson next season, and he has good hands. He's not Randy Moss, but his style of play has the same impact that results in spreading out the opposing defense. With Lloyd running 40-to-50 yard down field routes, Lynch, Graham and Doug Baldwin will be open frequently from short and mid range.
