Bevell is implementing an offense similar to the one Mike Holmgren ran in Seattle when Holmgren pushed the team to make Carlson a second-round draft choice.
That angle still might come into play, but Carlson isn't the only receiving tight end the Seahawks are considering as they move through the early stages of training camp.
Zach Miller, who played under Seattle assistant head coach/offensive line Tom Cable in Oakland, is visiting Seahawks headquarters. The free agent has missed only two games in his four seasons and has 226 receptions, including five for touchdowns last season.
The Seahawks have so far targeted free agents with ties to their coaching staff as they cram for the regular season during a cramped post-lockout time frame. Coach Pete Carroll has said the familiarity is important in getting players up to speed. The Seahawks also hope to target younger free agents in most cases. Miller is 25.
Carlson, 27, has seen his reception totals decline every year amid changing schemes, quarterback injuries and severe issues along the offensive line. He reemerged in the Seahawks' wild-card victory against New Orleans last season as the team used play-fakes effectively. But a concussion suffered during a face-first tumble against Chicago one week later ended his season.
Miller's production has remained steady. He would upgrade the position considerably for Seattle.
