The last time Derrick Johnson played the Chargers he had 9 total tackles. With the Chiefs offense so bad he may see even more time on the field this week. The Giants should try to run at Chaney, it's the soft spot in the Eagles defense. Chaney has had decent tackle numbers through 2 games.
I think Johnson would be the better play here. He should see a ton of tackle chances in the second half of this game. I think the Giants will be in comeback mode early into the 3rd quarter and there dismal run game will be abandoned.
Thanks
