He is young and a developmental player... If it took D-Law 4 years to emerge, it will take Hill some time to develop as well. Very few "instant impact" players in the NFL. That said-- you can see that Hill has great athleticism. He needs to grow in understanding the NFL game, as well as developing core strength and an anchor to not get pushed around.
Gonna be a couple years before we can determine what this kid is at the NFL level. We have been spoiled by a series of great first round picks that have stepped in and contributed. This pick was never about the short term impact-- but about having a guy that can grow into an elite disruptor at the 3Tech.
