The only thing worse than being frustrated is being frustrated about being frustrated. 

That must be how Tennessee Titans running back Chris Johnson -- a former 2,000-yard rusher -- feels heading into Sunday's duel with the Detroit Lions. The back formerly known "CJ2K" has just 21 yards this season and isn't exactly thrilled about his lack of production.

"I'm not the guy to sit here and be the guy that points fingers," Johnson said (via MLive.com). "It's a situation where I'm only going to be as good as my line is going to be, so we have to work together and get better together.

"I don't think I missed no big plays or anything like that. It's just a situation where we really haven't had the opportunity to stay on the field and really get into the running game."

MLive.com's Justin Rogers noted that it seemed like Johnson was passing blame on his offensive line, which, quite frankly, has been somewhat offensive this season.

If the Lions are to down the Titans, Johnson has to be stopped, regardless if he's having a slow start. The guy is blazingly fast and is one of the top backs in the NFL if you're basing talent on pure athleticism alone.

Former Detroit Lions great Herman Moore noted in his weekly column on WXYZ.com that Johnson is a load to handle and that the Lions should closely monitor him.

And by the sound of it, Lions tackle Cory Williams plans on stopping Johnson and keeping him from rebounding from two bad weeks Sunday. 

"We're going to try to make it even more frustrating," Williams said (via MLive.com's Rogers). "We try to take advantage of things like that."
