STRENGTHS - Stewart is well-built with the natural bulk and strength needed to address and defeat blockers inside. He flashes the foot quickness and speed to make plays outside the box in pursuit. He can be physical with receivers running through his area and knock them off line with passing jabs.
WEAKNESSES - Stewart displays poor instincts as he is consistently a beat late moving to the ball. He does not read his keys well and takes false steps that leave him out of position vs. cutbacks. On runs at him he tends to wait for the play to come to him which allows blockers to consistently get on top of him. He is not a physical player, as he tends to leave his feet and whiff on arm tackles and does not attack downhill. In zone coverage he tends to get stuck in no-man's land, as he does not get proper depth into area and seems to wander toward the LOS without purpose. When he does get depth he is late breaking on plays and allows too many catches in front of him.
SUMMARY - Jonathan Stewart was a very frustrating player to evaluate on film because physically and athletically he looks the part of an NFL starter, but his poor instincts and passive play severely limit his productivity. He tends to play stationary and allow blockers to engulf him when he should be able to challenge them at the LOS and clog up run lanes, and he does not bring his feet when tackling and misses too many arm tackle attempts. In pass coverage he struggles to consistently identify his assignments and again looks tentative in his movements. He'll likely be taken earlier than I have him graded because of his size, strength and athleticism, but if he doesn't learn to play more aggressively at the LOS and improve his read and react skills significantly, he is unlikely to develop into anything more than a backup 34 ILB.
