I didn't read the whole thread, so pardon me if I'm restating something. But, the Chargers first year of the 3-4 last year wasn't that great in alot of respects. They played a similar, vanilla style defense, and got VERY little pass rush from their defense. I've read articles stating how this year, with the team being more familiar with the system, and having better pieces in the 3-4, they've been able to mix things up alot more.
We've got alot of new starters, and rookies contributing on defense. This is the very 1st year of the 3-4, and we've had significant injuries to our LBs, which is the most critical position in the 3-4. Combine the vanilla scheme, with the injuries to LBs, forcing Ware into more "non-pass-rushing" responsibilities, and it's no wonder Merriman is having a better year than Ware. No need to get off the Ware bandwagon 14 games into his career.
