The Facts: Detroit is signing Willson to a one-year contract worth $2.5 million, according to a source informed of the decision.

Diehards Line: Signing Willson comes after the Lions released former first-round tight end, Eric Ebron, ahead of the new league year. Willson, an Ontario native, doesn't replace Ebron's pass-catching production (89 career receptions in five seasons in Seattle) but is a big upgrade as a run blocker. With the Lions hoping to turn a putrid run game around, improving the blocking from the tight end position became essential. Willson joins 2017 fourth-round rookie Michael Roberts atop the Lions' tight end depth chart. It's a position the team is likely not done addressing this offseason, but Willson scored four TDs on 15 receptions last year; it would be interesting to see him get more targets.
