Hill's main two problems remained a problem. Yes, he did flash some ability to penetrate and yes, he does hustle, but he also has a bad habit of coming up high out of his stance, which allows the offensive lineman to gain leverage and drive him out against the run ... which contributed to our run-defense woes. Similarly, he doesn't stay square, which allows the offensive lineman to turn and steer him. This effectively negates him against both the run and pass.
Hill's potential is in that he's a big man with a quick first step, but if he doesn't win with that burst, which hasn't happened often, the offense has the advantage because he plays with poor technique. Gotta stay square and stay low.
One of the main reasons Odighizuwa is gaining some preseason praise is that he plays with great technique/leverage. That helps him overcome the fact that he's not a big man, although he does have a decent first step.
