I wouldn't say they did fine, but I wouldn't say the d-line was bad either. The Lions had a solid effort against the run, but the pressure needs to get better. I'm more willing to say the Bucs played a fantastic game as far as pass blocking than I am to say the Lions played a bad game. The line didn't put any pressure on Freeman. One thing to get sacks, but the pressure was hardly there at all. One thing I've noticed about Avril is he's an edge rusher almost exclusively. Maybe that's by design though so they force the QB up into the pocket towards Williams and Suh, but I rarely if ever see Avril try to get inside the tackle.
Some might be content but the d-line could have performed better. Sometimes however you just have to say the opponent did a great job . We'll see over the course of the season.
