Honestly people don't understand what he was drafted for. He IS one of the best linebackers in pass coverage in the NFL if not the best. He is average against the run. Makes some plays but over pursues a lot.
With the more athletic tight ends like kelce and the amount of crosses teams run now he is invaluable in this D. 2 safties deep leaves a big hole in the middle and you need a long fast LB (or 2) to get depth answers take away the middle.
He's improving against the run and has made some great sticks in the last few weeks...but please pay attention to his primary purpose and see how many catches NE tighends got last weekend and see how he will be used against Pitts this week.
