Drop DJ Smith?

Is it ok to consider dropping DJ Smith for up and coming studs from injury such as
Angerer or Colin McCarthy? Despite the good matchup, DJ Smith only produced 4 tackles. AS Hawk and CJ Mathews seem to get more tackle numbers over DJ Smith.

ROS, I'd rather own McCarthy. But he may not be back until next week. Same thing with Angerer. I'd rather have McCarthy than Angerer, however.
