I can't recall, either way - but based on Phillips insistence on playing to his players strengths, it may not be the same here anyways. I have been able to gather, from trollling the Chargers forums, that he does something Parcells always preached, but mostly only payed lip service to - and that's substitution. He would rest Jamal Williams sometimes leading up to the half, when they were in their nickel trying to play a soft zone to prevent a quick score from the other team before half. He'd take out anyone, even Merriman, to keep them fresh. With the depth we *allegedly* have along the front seven, that could be a real boon for him.
But the fronts - I dunno. My guess is that varies depending on whether Jamal was on the field. They could play a 2 or 3 man nickel front with him, but probably had to go 4 without.
