Bass is a good call, but you're probably right in thinking that we can't get him.
We need a solid 4 so badly, and it may be worth moving someone like Adam to get one. I don't see us getting any immediate help at that spot from the draft unless we win it. It's all about 5/20.
I don't think we need Gordon, but the other two are intriguing. I used to be very pro-Duhon, but now I'm a little worried about him after hearing some rumors in one of the other threads (the "Offseason Rumors" thread). TT has always struck me as a bit of a punk, but a guy can go through a lot of maturation in the couple years after leaving college.
