No thanks... I like the three guys we have that are expected to start in Shanle, Vilma, and Fujita. Shanle had a very good 2006 when the DLine played well. He had a bad 2007 when they didn't. The same could be said about that pass defense, where they ranked 3rd in the league in 2006 despite all the plays given up by Fred Thomas.
I would focus on fixing the depth along the DLine and try to draft Dorsey or Ellis in the first round. I would also focus on fixing that OLine. They struggled quite a bit last year too.
