Jimmy Graham, Luke Willson give Seattle top tight-end duo

Here's a look at the tight end position for the Seattle Seahawks heading into training camp:

Locks: Jimmy Graham and Luke Willson

Graham, obviously, is the exciting new addition to a talented offense. He is one of the best tight ends in the NFL and will add a dimension to the offense that is hasn’t had in the past.

At 6-foot-7, 270 pounds, Graham is a huge target and also a bit of a hybrid who often lines up as a wide receiver. He is a nightmare for defenses, too quick for most linebackers and too big for many defensive backs. Graham’s best asset is his ability to make tough catches in the red zone. Of his 51 career TD receptions, 40 came in the red zone.

His one weakness is blocking, but the Seahawks’ coaches say he is committed to becoming a better blocker for a team that relies heavily in its running game with Marshawn Lynch.

Willson is much like Graham and a speedy tight end with excellent pass-catching skills, but he also was much improved as a blocker last year. The Seahawks often line up in a double tight end set, and these two guys should complement each other.

Likely: Cooper Helfet

Helfet (6-3, 240) spent two years on the practice squad before finally getting a chance to play last season, making 12 receptions, including two TDs. The coaches love his work ethic and his ability to contribute on specials teams. He’s well-liked by his teammates and has taken over the role that former fullback Michael Robinson had as the unofficial spokesman for Lynch when Lynch isn’t talking, which is most of the time.

Bubble: Anthony McCoy

It’s hard enough for a player to come back from one Achilles tendon surgery, but McCoy is trying to come back from two of them. He suffered his second Achilles tear last year in training camp and missed the entire 2014 season after sitting out all of 2013 with the same injury. McCoy may be the best blocker of the bunch, but that may not be enough to earn a spot.

Longshot: RaShaun Allen

Allen was a rookie last season out of Southern who started out on the practice squad and played in one game because of injuries at the position. With the addition on Graham, it’s a major uphill climb for Allen to earn a spot.
