He reminds me a lot like Demetrius Dubose. A lot of people were wondering why he wasn't starting as a sophomore full time, but he still had to learn about tackling angles, pass coverages, and not overpursuing.
In the mean time, Don Grimm filled in very nicely during 1989 for an injured / suspended Mike Stonebreaker, and also filled in quite nicely in 1990 for Dubose while he was learning on the job. He didn't have nearly as much athleticism or talent as Dubose did, but he was one hell of a smart player.
Even in 1991, Dubose still had some relapses of overpursuing the target, especially during the Michigan and Penn State games.
It wasn't really until 1992, his senior year, that Dubose became the total package.
