Injuries likely led to this move by Seattle, and Seisay is exactly the type of cornerback they tend to covet: well-sized, athletic, with good length, and underrated. While Seisay probably won't be a regular rotation guy anytime soon, he'll be a very solid development prospect who can help out on special teams right away.

The Lions have a glut of quality cornerbacks so moving Seisay clarifies things a little for them while providing another pick for next year's draft. Seisay showed some promise while in Detroit, but the Lions' corner corps is already deep.

While Seisay is a definite sleeper for down the road, he has little to no fantasy upside for the coming campaign (even in fantasy leagues featuring Individual Defensive Players).
