He reminds me a lot like Brian "Hambone" Hamilton, who rotated between DE and DT in 1992, and was an excellent one.
A lot of people were wondering why he and Jim Flanigan weren't playing extensively in 1991, since both of those guys were excellent stalwarts in 1992 and 1993. The answer was that they weren't ready yet, and Flanigan especially wasted time trying to stay at linebacker for his first two years.
Even Devon McDonald needed a couple of years before he turned into a good DE for us.
I trust Coach Washington to make the right decisions.
