The Detroit Lions have certainly helped themselves at linebacker and in the secondary so far in free agency, but they still have a glaring hole at defensive tackle.
The game plan that general manager Bob Quin and head coach Matt Patricia have stuck to has been one of finding pieces that fit their new multiple defense which will shift from a 3-4 to a 4-3 depending on opponent, in-game adjustments or possibly even which way the wind blows.
Yet almost every game is won in the trenches and so far the Lions have done nothing to fortify the defensive tackle position which became a weakness after Haloti Ngata went down to injury this past season, then left town for Philadelphia as a free agent just a few days ago.
