The tight end position has never truly been a featured part of the Seahawks offense, regardless of which head coach was running the ship. It took on a bigger role in the west coast offense Mike Holmgren imported in 1999, but never resulted in any TE stars being born. At times, the position served as more of a 6th offensive lineman, rather than an integral part of the passing game.
But in looking at all the players who have suited up at the tight end in the 40 years since the birth of the Seahawks, there are clearly 5 who stand above all the rest:
#5 Jerramy Stevens
In terms of pure talent, Stevens might be #1.
