It's not my proposal. Just saw this article over on NFL.com suggesting it.
Secondary issue in Detroit
The Lions have a weakness at safety, and it needs to be addressed if they're going to make a deep run in the playoffs.
Detroit finds a trading partner in the Jets. New York carries 10 defensive backs on its roster and can afford to deal safety Brodney Pool. In return, the Jets get Nate Burleson, who would become the third receiver with Mason now in Houston.
Now I don't disagree that they could use some help in the secondary. However, even with as good as Young has played I'm not convinced he should be counted on to replace Nate at this point. Plus it then begs the question of who gets Young's spot if you make the move?
