I think nothing scares a team more than speed. Williams is a good receiver, but it's his quickness that most commentators seem to dwell on.
Sinkfield has that same kind of speed, as well as great hands. He made some terrific clutch catches while he was here..
With Toliver on one side and Sinkfield on the other, and Banks sweeping over the middle, could make for some nightmarish planning for opposition DC's in this league.
I don't see ANY db catching any of those players once they get a pass.
