Sawed-off, one-gapping nose prospect for an even-front defenses. Stills plays an extremely active brand of football with desired short-area foot quickness and the leverage to play through blocks when he gets into gaps. He works with adequate play strength at the point of attack, but his lack of mass and length suggest he better be in a scheme that keeps him attacking upfield or he could be swallowed by NFL size. He can be way too undisciplined at times, but coaching should be able to help in that area. Stills warrants consideration as a rotational nose in an upfield, 4-3 scheme.
Productive linebacker with good feel for blocking schemes and where running backs are eventually headed. While Fields' patience prevents him from making ill-advised advances that would pull him out of position, he will need to balance his patience with a more controlled aggressiveness when it comes to playing ahead of play designs. He has the instincts to take more chances and will most assuredly need to due to his lack of desired size and play strength. Fields' inconsistent tackling and below-average third-down potential could further hurt his chances if he doesn't improve his aggression level against the run.
