Ed Oliver thinks last Sunday was the first time in his life he hasn't started a football game.

It's the first major setback for the first round pick, who has just one sack midway through his rookie season.

"Frustrating to say the least. Statistically it hasn't been, but the proof is in the pudding. It's not like I'm not winning. It's just the stats just aren't there,” said Oliver.

Oliver admits there's still so much for him to learn, and it's mostly about the small details of the game and bringing it all the time.

"It's just not me not being capable of doing my job at a high level. I can do that and it's on film and I have shown that. It's being consistent. So until I become consistent and become every play…that's the big hold-up right now is consistency and not every other play, but every play,” said Oliver.

Sean McDermott and Leslie Frazier earlier this week echoed what Oliver's saying, making this more about what Jordan Phillips has done opposed to what Oliver hasn't. Phillips’ six sacks are the most by any defensive tackle in the NFL, and more than he had total the first four seasons of his career — a product of what Phillips says is just more opportunity.

"I haven't even tapped into what I can do yet. So, we'll see how it goes, but yeah, I have a lot more to give...just be more dominant. I haven't really taken over a game yet. I've taken over a half in the Tennessee game, but I want to take over games. I want to do be a difference-maker and be able to help this team win any way I can,” said Phillips.
