Donald has been the prototype at the position, but it's easy to see that he's a generational talent and unlike anything that we've seen before.
Outside of that, the talent at the position is the best that it's ever been. Names such as Fletcher Cox, J.J. Watt, Akiem Hicks, and Chris Jones are just a few of the top of the line talents across the league. The talent gap between lineman on either side of the ball continues to become wider every season. With the caliber of athletes entering the league yearly, it's easy to see why.
Here are the top traits to look for when evaluating interior defensive lineman:
1. Understanding Role and Scheme Fit
2. Hand Usage
3. Instincts and Awareness
4. Size-Speed-to-Power
