Today's DMN indicates that Willis won't play this year. Thank goodness. Playing Willis at this point would be stupid. Now, the question is whether Phillips will get a chance to play these last three games. I think he should; I doubt he does.
Backup DE Kyle Griffin will miss the rest of the season. Griffin has seen playing time in the last six games. Griffin hasn't really shown up much in the stats, but his absence hurts the depth of the defense, which has never been very deep.
